Can you explain why you want to upgrade just the kernel?  Or perhaps
that is not what you mean.  An upgrade to Ubuntu 14.04 does much more
than just upgrade the kernel.  It upgrades all the other software too,
so no, you cannot easily go back, you would have to re-install 12.04.

If you want to make sure 14.04 will run ok on your machine then try it
by booting off the downloaded 14.04 image on DVD or, preferably, USB
stick and make sure it goes ok.  To be ultra cautious you could create
a 10GB partition on the disk, install 14.04 onto that partition, and
then you would be able to boot into 12.04 or 14.04.  When you have
convinced yourself it is ok then upgrade 12.04.
