You can run a 4.4 kernel on a 4.2 userland with no problem. On some of
my production boxes, I'm running a 4.4 kernel on a 4.0 userland :) You
should be able to build a 4.4 kernel, copy it to /kernel.test, and do a
quick reboot to see if it works. That way you can fall back to the 4.2
kernel if you have problems.
