You _can_ hook into MediaWiki at the "show edit page" event and do some cool 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 ?
