I never got around to doing a final mow in the fall, and I'm wondering
if
there would be any benefit or if it would hurt my lawn if I did it now.

It is currently a couple degrees below freezing although last night it
went
to 10 below (Celsius).

OK as long as grass is no longer frosted/frozen. Even walking on frozen
grass can damage it.

I don't know about the first sentence but I've walked on many a frozen
lawns (without scuffing my feet) and never saw damage to them over the
years. I believe the reason is that as long as the root system is
well nourished and undamaged, what happens above ground is not that
important. Our frost depth was well below the roots and our lawn
never seemed to suffer from being frozen.

Walking on frozen grass will not harm the HEALTH of the grass, but it can
(temporarily) damage the APPEARANCE of the grass. When stepped on, the ice
crystals in the leaves puncture the epidermal cells, potentially leaving
brown spots.
