You _can_ hook into MediaWiki at the "show edit

things with it, but there's no good way to know the article from which the
user came - which would be a prerequisite for modifying said article's
links. Technically you could use the browser's provided "referrer", but
this is unreliable (proxies) and easily spoofed or disabled.
All of that aside - it's still a hard problem because of the
nondeterministic nature of wiki rendering and the complications that arise
from template transclusion. Even if you know the referrer (as in an Edit
Preview), the process of determining where in the wikitext a particular link
was generated is daunting.
Maybe creating a redirect on this page is a valid solution ?
