Yes, but this is extermely machine dependent.

If you peer closely at the 4.2 or 4.3 BSD signal manual entries,
you will find something called `sigcontext'.  This includes enough
of the call frame so that you can alter the return point, and the
stack pointer and/or frame pointers if necessary.  The way to do
this is no doubt quite different on a Pyramid than on a Vax.
