I don't think that's currently possible without writing a little lisp
code.  There is an org-follow-link-hook but it doesn't seem to be
executed for all link types - only browser urls if I'm reading the code
correctly.

The following patch seems to fix it so it executes for plain file links
too.  You can probably create a function that goes to the point and then
narrows the text around the point using this hook.

I tested this by setting the hook with 

(setq org-follow-link-hook 'hide-other)

HTH,

Subject: [PATCH] Enable org-follow-link-hook for all link types

This hook was only executing for browser links.  Now we always execute the hook
after visiting a link assuming no error occurs.
