The list from check.tp.o is built by active measurement -- it builds a
circuit through each exit relay and finds out what IP address it used
for making the exit connection. Your Tor client only knows the IP address
that the exit relay advertises for incoming connections, and if the exit
relay is multi-homed (as some are), they could be different.

So no, that list of actual exit addresses is not available via the
control port, because your Tor doesn't know it.

You might enjoy
as a more fun way to interact with the exit-addresses list.
