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.

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.
