No, you cannot. There are two reasons for this, one legal, and one
technical.
First of all, by your own admission, you have an OEM license for
Vista. An OEM license must be sold with a piece of hardware (normally a
motherboard or hard drive, if not an entire PC) and is _permanently_ bound
to the first PC on which it's installed. An OEM license, once installed,
is not legally transferable to another computer under _any_ circumstances.
To even attempt to do so would be the equivalent of your telling the
world that your given word and your signature on a contract are completely
without value, never to be trusted.
Secondly, if the OEM CD was designed by a specific manufacturer, such
as eMachines, Sony, Dell, Gateway, etc., it will most likely be
"BIOS-locked" to install only on the same make/model computer for which it
was designed, as an additional anti-piracy feature.
You need to purchase a separate Vista license for each computer on
which you install it. (As long as you have multiple identical licenses,
it doesn't matter if you use the same CD for the installations, as long as
you use a different license each time.)
Just as it has *always* been with *all* Microsoft operating systems,
it's necessary (to be in compliance with both the EULA and U.S. copyright
law
http://www4.law.cornell.edu/uscode/17/117.html), if not technically)
to purchase one WinXP license for each computer on which it is installed.
(Consult an attorney versed in copyright law to determine final
applicability in your locale.) The only way in which WinXP and Vista
licensing differs from that of earlier versions of Windows is that
Microsoft has included a copy protection and anti-theft mechanism, Product
Activation, to prevent (or at least make more difficult) multiple
installations using a single license.
