No, I don't think that it does. I tested this perhaps a year
ago, out of curiosity as much as anything else, and could not
find a way to make it work.

I did not find one at the time.

I did find that one router on my company's network (I think it
was a Cisco) transformed the 802.2 LLC/SNAP headers into Ethernet
II headers as packets passed through it, which effectively acted
as a gateway to allow Linux to talk IP over 802.2 LLC/SNAP. But
I don't think that it translated in the other direction.
