Downgrading vista to xp can I use the vista key??

Can someone confirm (or deny) this please. I have read a post on another
forum that claims if you have a legal copy of Vista you can downgrade to XP
and use the Vista key.

If this is possible will it apply to an embedded OS and will it be like for
like ie vista pro for XP pro??

Thanks in advance.
