Ubuntu is based on Debian and uses the same package management system.  
There's nothing stopping you from installing a Debian kernel on an Ubuntu 
system.  You can configure apt repositories to have different priorities and 
have a Debian repository used for the kernel packages.

Debian user-space usually works with kernels from the previous and the next 
release.  For the things I work on I always try to make that work.  There have 
been some exceptions (like udev and systemd depending on new kernel features 
in some versions and adding the "file:open" permission to SE Linux) but it's 
most likely that Debian 9 will work with a Debian 8 kernel and it's possible 
that Debian 10 will work with a Debian 8 kernel.

You can cross-upgrade from Ubuntu to Debian as many packages have similar 
version numbers, but that might be too inconvenient for you.  A reinstall to 
Debian might be best.

Also Debian does work well with a Fedora or CentOS kernel.  It is a little 
more effort to set it up so you might not want to do it.  But it's technically 
possible if that gives you the best result.  I've done it before.

Different distributions have different policies about backporting features and 
supporting old versions.  CentOS has a longer support cycle so it might be an 
option to use a CentOS kernel with Debian.

As an aside I've talked to a client about retiring some non-PAE systems at 
some future time because CentOS is unsuitable and we don't want to support 
mixed OS systems.  We are talking about a replacement cost of $50K for those 
systems which will probably happen a couple of years after Debian 8 support is 
dropped.
