No, but I'd expect it to work OK.

Actually, I wouldn't expect that to be necessary.  The most likely use
of initramfs is to have just enough contents to make it possible to boot
into a more normal userspace; we're not talking about more than a few
hundred Kbytes.  The main things that belong there from a functionality
standpoint are udev, dm, and kinit, and they don't amount to much.
