It is safe..  but for extra safety, I always leave a couple older kernels on 
just incase i need to boot back. I always keep original BOOT kernel, and then 
my SMP+Bigmem (over 2 gigs of ram)..  If you're multi proc or hyperthreaded, I 
don't see any reason to keep the non-smp kernel.

But, I would save at least one last known working kernel while you use your 
new one for a while.
