I have a 56 Sam with 37mm Soma New Express tires under longboards, and
there's plenty more room. If the Marathons are really 3mm fatter, I'd
think it would be fine.

Yes, you can put 40mm Supremes under fenders. Have done it on both the
original green Hillborne and my present blue. The newer bikes have enough
room that I could easily put on 45mm tires and maybe even 50 if I was
careful. (Which I am not, so won't).
Can't help on the other part.
