It wouldn't be on a Samba wikipage if it wasn't supported.

You are missing something ;-)

root at dc4:~# samba-tool spn list devstation
devstation
ERROR: User devstation not found
root at dc4:~# samba-tool spn list devstation$
devstation$
User CN=DEVSTATION,CN=Computers,DC=samdom,DC=example,DC=com has the following servicePrincipalName: 
	 HOST/DEVSTATION
	 HOST/devstation.samdom.example.com

You are missing the '$' on the end of the computer name.
