No, because Mach is NOT "owned by GNU."

Perhaps you might find it useful to look at the *real* licensing
information about Mach, which was produced at CMU, and therefore owned
by Carnegie Mellon University.

Subject: How to get a Mach license
Author: Mary R. Thompson
Date: Oct 1994
--------------------------------------------
A Mach 3.0 license is required in order to get the complete
BSD 4.3 compatible Mach 2.5/3.0 release. This is a rather
obsolete system dating from 1992 which is only available for 
i386/486 platforms and supports the Tahoe level release of 
BSD 4.3. 

CMU does not charge for this license, but with the cessation
of Mach Project support, it may take quite a long time
to process the paper work. 

Before you can get a Mach license, you must have a Fourth 
Berkeley Software Distribution (4.3BSD) license. That license
in turn requires that you have a Unix source license. Information
about the BSD license can be obtained from <bsd-dist@cs.berkeley.edu>.
These licenses were reaonably priced for educational institutions
but not for individuals or small companies.

If your institution already has a 4.3BSD and you have a lot of
patience, you may contact mach-coordinator@cs.cmu.edu and 
ask for two signed copies of the Mach license to be mailed to you. 
Please include the official name of the University/Company to which 
the license is to be issued and a mail address to which it can be sent.
We cannot e-mail or FAX licenses because they must have "real"
signatures on them.

A sample of a Mach license is included if you wish to check if your 
company would be willing to sign it.
