If you mean one "koji build" results in two builds being created in 
Koji, then no that is not currently possible.

This sounds like something that could easily be handled with a Makefile 
target though.

Create your separate dist-centos4 and dist-centos5 build/dest tags and 
targets.  Have a "make build" generate the appropriate SCM URL and call:

koji build --nowait dist-centos4 $SCMURL
koji build --nowait dist-centos5 $SCMURL

Assuming you're using %{?dist} in your specfiles and have the 
buildsys-macros defined correctly (and uniquely) in the -build tags, 
this will create 2 separate builds in different tags from the same sources.
