I have some odd token-ring type adapters that have been floating around

I think that both 10Base2 and 10Base5 have some fairly hard requirements
on the cable / RF distance the card can be from the common bus. As such
I'm fairly certain that you couldn't have very much cable at all between
the coax bus and the transceiver.
Remember, 10Base5 had taps with active electronics directly next to ~>
on the coax bus and then completely separate AUI connection using
completely different technology on a service drop cable.
So, no, I'd bet lunch that you couldn't run 10Base2 over the adapters
that you have.
Aside: You /might/ be able to use two of them back to back as a part of
the larger 10Base2 bus, but not the lobes.
I cannot remember where it came from, but the highschool I attended
in the 90's was an IBM case study of sorts as I was told at the time
and it was excessively wired up with token-ring, and also had a
television in every room linked back to a fully equipped studio that
was used for live news broadcast style video morning announcements... I
wonder if it used this system to share the wiring.
Interesting.

That's a BNC, not an F connector.
It also doesn't seem to have any data cable connected to it. Is it
supposed to be there? Or are the adapters that you have specifically
meant to re-use / abuse the horizontal in-wall cable explicitly for the
signal going over the BNC connector?
My assumption of the F-Coupler was that it could be used at the same
time as Token Ring data connections.

Yeah I just took a minute to search after all these years, it seems these "Red" ones are for 3278 terminals, Blue would have been for ethernet, and there are some others yellow,green etc matching for other types.
Found a random listing on ebay while doing an image search that took me to some IBM part numbers.
