That's kind of what I thought it meant :^( Guess I really will have to get
the PDP-11/23 up and running if I want to play with this board.

You mean like "this board isn't compatible
with a 22bit backplane" kinds of
things. (which it isn't BTW, that's what the note is about BDAL18 is
address line 18 which is called BC1 on 18 bit backplanes.)
I'm not sure how you would use it in a system with a 22 bit backplane. Even
if you pulled the address line off the back plane the board's CSR registers
would show up in memory space and you would have bus contention.

Out of curiosity is there anything I need to know

My plan has been to plug it into my PDP-11/73 which resides in a BA123.
Also is there any way to test one without having anything connected.
