That would work fine.  You could still log in to the console and run the 
Asterisk console (asterisk -R) to watch things work, which is instructive.

Yes, runlevel 1 (or "single user mode" as it is often called) is 
primarily for debugging or administration, and is set to run as few 
background programs ("daemons") as possible.  Asterisk may depend upon 
some of these daemons (email, cron, syslog, to think of of a few), so 
runlevel 3 is still your best shot.
