Yes, more or less, but it's actually even easier than that. I would recommend:

1. As root, type "rpm -q kernel" at the command line. This will show you a 
list of the kernel packages you have installed. It will look something like:

[root at wilbur root]# rpm -q kernel
kernel-2.4.22-1.2115.nptl
kernel-2.4.22-1.2135.nptl

2. Pick the one you want to get rid of. In the example above,   
"kernel-2.4.22-1.2115.nptl" is the old one. Still as root, type
"rpm -e  kernel-2.4.22-1.2115.nptl".

This will remove that particular kernel package and edit grub.conf for you. 
The only caution: make darned sure that you're not removing the kernel that's 
currently running (use the command "uname -r" to check which one that is) or 
the only one that will boot the machine.

Have fun!
