The long and short of it is that they'd have to go looking for it.
There are ways to diagnose the operating system of a remote machine by
sending specific packets to it, and diagnosing the response. 'nmap' for
example will do this. Fortunately, nmap mostly runs on *nix boxes.
Other than that, if you turn off all the services in Linux, there's
nothing that screams "I am a linux box". If you *send* e-mail however,
you're going to be advertising, since most mail clients brand the
message in one way or another.
I'd quietly find out if the 'policy' is just because they don't want to
support Linux, or if they're afraid of you employing hacker tools.
