As indicated in the comments, the original answer was written for Bootsrap 4 Beta 2. The released Bootstrap 4 version requires two changes in the markup/css. Hence the update.

In Bootstrap 4 you can achieve that functionality with the following markup.
(As the built-in snippet viewer mixes up things sometimes when css @media queries involved, I've created a Codepen too.)

Compared to BS 4 Beta 2 there are these two required changes:

First, the way the tabs are hidden are changed: Earlier .tab-panes opacity was managed by the .fade class, but in the released verion it is the .fade:not(.show) selector, which has higher precedence. So, to override the opacity .tab-pane needed to be changed to .tab-content > .tab-pane in the css.
Second, the handling of collapsible groups are changed as well. Previously it was the toggle button which required the data-parent attribute. However since the release version data-parent needs to go onto the collapsible element.

The updated code for Bootstrap 4.1.3 is like so:

HTML

<div class="container">
    <ul id="tabs" class="nav nav-tabs" role="tablist">
        <li class="nav-item">
            <a id="tab-A" href="#pane-A" class="nav-link active" data-toggle="tab" role="tab">–A–</a>
        </li>
        <li class="nav-item">
            <a id="tab-B" href="#pane-B" class="nav-link" data-toggle="tab" role="tab">–B–</a>
        </li>
        <li class="nav-item">
            <a id="tab-C" href="#pane-C" class="nav-link" data-toggle="tab" role="tab">–C–</a>
        </li>
    </ul>


    <div id="content" class="tab-content" role="tablist">
        <div id="pane-A" class="card tab-pane fade show active" role="tabpanel" aria-labelledby="tab-A">
            <div class="card-header" role="tab" id="heading-A">
                <h5 class="mb-0">
                    <!-- Note: `data-parent` removed from here -->
                    <a data-toggle="collapse" href="#collapse-A" aria-expanded="true" aria-controls="collapse-A">
                        Collapsible Group Item A

            </div>

            <!-- Note: New place of `data-parent` -->
            <div id="collapse-A" class="collapse show" data-parent="#content" role="tabpanel" aria-labelledby="heading-A">

@TimVermaelen what do you mean I can see you are right (i.e. this markup no longer works bootstrap v4.1.3) but I have moved `data-parent` around like a mad man and they still disappear (when in mobile) what am I missing? — Mr Heelis, Dec 10 '18 at 14:59
@TimVermaelen EG: shrink this down to mobile to see the bug https://codepen.io/anon/pen/JwoKOY#anon-login — Mr Heelis, Dec 10 '18 at 15:54
@dferenc https://codepen.io/dferenc/pen/YYyjYJ is your original 4.0.0 beta.. (works only in 4.0.0) the version I link here https://codepen.io/anon/pen/JwoKOY#anon-login is 4.1.3 (and is not working) — Mr Heelis, Dec 10 '18 at 16:04
@MrHeelis, please check your bootstrap version first (js & css), as it seems to be still beta 4.0.0. — Tim Vermaelen, Dec 10 '18 at 18:49
@TimVermaelen thanks for the note! While the change in `data-parent` is indeed important, it was more the change in the css which rendered the OP out of date in the first place. — dferenc, Dec 10 '18 at 22:15

Current Bootstrap 4 versions, suggests the data-parent should be put on the collapse containers.

To add accordion-like group management to a collapsible area, add the data attribute data-parent="#selector".

<div class="container">
    <ul id="tabs" class="nav nav-tabs" role="tablist">
        <li class="nav-item">
            <a id="tab-A" href="#pane-A" class="nav-link active" data-toggle="tab" role="tab">–A–</a>
        </li>
        <li class="nav-item">
            <a id="tab-B" href="#pane-B" class="nav-link" data-toggle="tab" role="tab">–B–</a>
        </li>
        <li class="nav-item">
            <a id="tab-C" href="#pane-C" class="nav-link" data-toggle="tab" role="tab">–C–</a>
        </li>
    </ul>

    <div id="content" class="tab-content" role="tablist">
        <div id="pane-A" class="card tab-pane fade show active" role="tabpanel" aria-labelledby="tab-A">
        <div class="card-header" role="tab" id="heading-A">
            <h5 class="mb-0"><a data-toggle="collapse" href="#collapse-A" aria-expanded="true" aria-controls="collapse-A">Collapsible Group Item A</a></h5>
        </div>
        <div id="collapse-A" class="collapse show" role="tabpanel" data-parent="#content" aria-labelledby="heading-A">
           <div class="card-body">[Tab content A]</div>
        </div>
    </div>

    <div id="pane-B" class="card tab-pane fade show" role="tabpanel" aria-labelledby="tab-B">
        <div class="card-header" role="tab" id="heading-B">
            <h5 class="mb-0"><a class="collapsed" data-toggle="collapse" href="#collapse-B" aria-expanded="false" aria-controls="collapse-B">Collapsible Group Item B</a></h5>
        </div>
        <div id="collapse-B" class="collapse" role="tabpanel" data-parent="#content" aria-labelledby="heading-B">
            <div class="card-body">[Tab content B]</div>
        </div>
    </div>

    <div id="pane-C" class="card tab-pane fade show" role="tabpanel" aria-labelledby="tab-C">
        <div class="card-header" role="tab" id="heading-C">
            <h5 class="mb-0"><a class="collapsed" data-toggle="collapse" href="#collapse-C" aria-expanded="false" aria-controls="collapse-C">           Collapsible Group Item C</a></h5>
        </div>
        <div id="collapse-C" class="collapse" role="tabpanel" data-parent="#content" aria-labelledby="heading-C">
            <div class="card-body">[Tab content C]</div>
        </div>
    </div>
</div>

DEMO

FYI _ Tim, great work but with 2 slight bugs 1) if you pick tab C ([Tab content C]) or Tab B ([Tab content B]) in large then resize down Accordion Title A (and or Title C) disappears, also when you select a "tab" or "accordion" in either mode, the content selected isn't preserved in the displayed accordion/tab in resized mode — Mr Heelis, Dec 10 '18 at 19:32
Thank you for this. I'll compare them with my last integration tomorrow. Should be possible to sort this out with data-attributes only. — Tim Vermaelen, Dec 10 '18 at 19:41
Or today ^^ Issue related to CSS. Please note the changed selector `.tab-content .tab-pane`. — Tim Vermaelen, Dec 10 '18 at 20:01

I made this bootstrap 4 tab to accordion using jquery.... I hope it works :)

function tabToAccordion(){
    var navTab = $(".nav-tabs"),
        tabContent = $(".tab-content");
        // hiding the navtabs
    navTab.hide();
    // appending each link to respective tab-pane
        navTab.find("li").each(function(){
            var destination = $($(this).find(".nav-link").attr("href"));
            var anchor = $(this).find(".nav-link");
            // removing unused attributes and adding tabContent-toggler class
            anchor.removeAttr("data-toggle role aria-controls aria-selected").addClass("tabContent-toggler").insertBefore(destination);
        });
    var tabToggler = $('.tabContent-toggler'),
    tabPane = tabContent.find(".tab-pane"),
    // get all classes in tab pane for further usage and replace tab-pane with empty data
    nonActiveTabPane = tabContent.find(".tab-pane:not(.active)").attr("class");
    tabPaneClass = tabPane.attr('class');
    tabPaneClass = tabPaneClass.replace(nonActiveTabPane,"");
    tabToggler.click(function(e){

        var destination = $($(this).attr("href"));
        // if not this element then remove active class
        $(this).parent().find(tabToggler).not($(this)).removeClass("active");
        //if not clicked destination then remove all other class except tab-pane
        $(this).parent().find('.tab-pane').removeClass(tabPaneClass);
        // now toggle active class
        $(this).toggleClass("active");
        // also toggle all other class in tab-pane
        destination.toggleClass(tabPaneClass);
        // if this element dont have active class then remove all other class from tab-pane
        if(!$(this).hasClass("active")){
            destination.removeClass(tabPaneClass);
        }
