    Sorry (god morning to me) just read your question and understood it this time.

    So you are asking the same child category has multi parents? so same sub forum lives in 2 different places?

    Generally not. You might be able to tweak some views, but at least the discussioncount in the categories will not be correct. But even that could possibly tweaked.

    You would need a plugin. In /applications/vanilla/views/categories/all.php there are those lines:

    $categories = $this->data('CategoryTree');
    writeCategoryList($categories, 1);

    The function writeCategoryList is defined like that:

    if (!function_exists('writeCategoryList')):
        * Renders a category list (modern view).
        * @param $categories
        * @param int $depth
       function writeCategoryList($categories, $depth = 1) {
           if (empty($categories)) {
               echo '<div class="Empty">'.t('No categories were found.').'</div>';
           <div class="DataListWrap">
               <h2 class="sr-only"><?php echo t('Category List'); ?></h2>
               <ul class="DataList CategoryList">
                   foreach ($categories as $category) {
                       writeListItem($category, $depth);

    You would need to copy that function under your plugin class and slightly change it. Find out the structure of $categories and change it the way you want. That should be all that is needed. But since it is dirty tweaking, there might be some unforseeable side effects ¯\_(ツ)_/¯
