But that has nothing to do with what openSUSE 13.1 requires.  It does
not support putting an older kernel version on it at all.  If you do so,
you get to keep all of the pieces that you end up with :)

You can almost always put a newer kernel version on a distro, and
openSUSE does support this if you run the Tumbleweed variation, which
handles any needed package updates and other system changes that a newer
kernel sometimes requires.  Fedora does much the same thing with their
releases, providing newer kernel releases over the lifetime of a release
cycle.

good luck,
