Generally speaking the kernel -> userspace interactions should be
safe. But if you grab a newer kernel (i.e. linux-yocto) from a
release, and pull it back to an older one .. you need the recipe
and associated build tool to match what that vintage build system

So you may run into a few issues on the build side, but at runtime,
it should be safe.
