Answer: yes, provided the tiles are light.
Cork is a light material, so we wonder if it will support tiling. Choosing a moderate weight tile is recommended to avoid peeling it from the cork support. With an abrasive paper, it is necessary to scrape the cork so as to degrease it well. Originally a layer of vinyl is present on this material, so care must be taken to remove it. Then, dust the cork well to allow optimal adhesion of the glue. The risk that the wall covering thus thought does not hold is relatively low. It is still essential to gauge the material on which the cork was originally placed. If the wall is healthy, laying the tiles directly on the cork is possible. If your wall has suffered from waterproofing problems, prefer to peel and treat everything. You too, send us your brico question
