I'd have to ask, but I'm 99.9% sure it's a "no" if money exchanges hands. If he wanted to produce it not-for-profit in an electronic format it "might" be ok, but there could be an issue with a print over electronic format.

Oh well, it never hurts to ask?
Did you plan on a map with any of the planets or their names in an identical location, the words "Draconis Combine, Federated Suns or Capellan Condeferation?" They're all trademarked.
Any original setting with non-trademarked material is the only legal way of replicating for profit. (At which point it's not BattleTech is it?) So no replication would have taken place.
