Wrong.  It may be possible to use the newer kernel from a newer version
of a distribution with an older base distribution on your system, but
there are other considerations.

Here's what you'd get with a kernel only upgrade:

- newer modules. 
- newer kernel.

Here's a few (not all) places you may get hungup:

- newer kernel usually needs newer modutils package.
- newer kernel may require newer mkinitrd.
- newer kernel may require newer fileutils.

Going with a custom kernel should work, so long as the major.minor rev
numbers are the same.  Still, there could be issues.

With a full upgrade of your distro to a new version of that distro, you
also get new libraries and header files, a new compiler, and all sorts
of bug and security fixes (but not necessarily the latest fixes).
