In other words, try to mislead CRAN.  If you are caught doing that, you 
won't get much sympathy in the future.

Why not just link to the copy of the vignette that is distributed with 
the package?  That will work even if your Internet connection doesn't.  
Just use a relative URL.  To link from vignette1.html to vignette2.html, 
use URL "vignette2.html".  They'll be installed in the same directory 
when the package is installed, so the relative link will work.
