The tag alias #74271 young_dom_old_sub -> younger_dom_older_sub has been approved.
Reason: None of the images for young_dom_old_sub actually have the tag old. Even for pictures specifically having a dominant_young and submissive_old (of which there are none), the tag conjunction should be used instead of having a specific tag young_dom_old_sub for it. Most likely the people using the tag just meant younger_dom_older_sub, hence the alias request.
EDIT: The tag alias young_dom_old_sub -> younger_dom_older_sub (forum #432843) has been approved by @Cinder.
