Probably not because it'll step on valid bootloader things with stale
copies. If you avoid stepping on anything in:
/boot
/etc/grub*
It might work... but you'll still have kernels that rpm database says
are installed that aren't installed; you'll have stale boot entries
for kernels that aren't installed and thus won't work. None of it will
get cleaned up on its own.
