backporting newer filesystems to older kernels is a nontrivial task.
Distros do it with a fair bit of effort and testing; non-fs-ninjas
usually do not.  :)

So yes, it's technically possible, but it's not a drop-in replacement.

(if you're talking about the userspace xfsprogs code, that's another
matter; newer xfsprogs & xfsdump should work fine with older kernels,
just build it and go)
