No. If you really want to do this, the accepted way is to create two 
programs that communicate by a documented message passing protocol (TCP 
or pipes are typically used, and command line options can be part of the 
calling interface.)

Generally, trying to find loopholes in the GPL is not looked on kindly 
by the open source community.

RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
