You can, and we have on two RHES3 production machines -- because of all 
the interdependancies on the shared libs, it's easier to simply install 
all the client RPMs, untarball the 4.x server into a location and run 
the install scripts, etc. It will read your /etc/my.cnf and make the 
libs over in /var/lib/mysql and so forth - a few minor mods to the 
init.d mysql script and you're done.

This mixed mode has been running like a champ, no problems.
