It's possible that there's still an old kernel installed, especially if 
this was an upgrade.

yum --showduplicates list installed kernel

will get you a list of all installed kernels.  If you have any old ones 
hanging around you can have yum remove them.  Then check grub.cfg and, 
if needed, re-run grub2-mkconfig.
