Kernels  It is not uncommon to run a Linux system with a kernel
that was compiled for another distribution. One reason for doing
this is the difficulty in compiling and testing a kernel to make
sure it will do what you require. It’s not THAT difficult for
someone who knows what they are doing, but if someone else has
already done the work then it seems like a waste to re-invent
the wheel. Sometimes it’s an issue of a driver that one
distribution supports but not another, copying the entire kernel
package from another distribution may be easier than compiling a
new kernel with the extra driver. Sometimes it’s a kernel bug,
if distribution A has fixed the bug and distribution B hasn’t,
then it’s often easier to install a kernel package from
distribution A when running distribution B.  Another reason for
running different distributions with the same kernel is Xen. If
you have a Dom0 which hosts instances for different
distributions as DomU’s then run
