It is possible. But it will take some work on your part to effectuate the
"run the builded tests on my other platform" part. The basic aspect is you
specify a program/script that wraps the execution of the tests to do the
aspect of running it remotely. To do that you specify the name of that with
"testing.launcher=<program>" (See
https://www.bfgroup.xyz/b2/manual/release/index.html#b2.builtins.testing).
I.e. if the program was "testonwin10.exe" you would do this:

b2 test testing.laucher=testonwin10.exe

The launcher is invoked with all the arguments that would be given to the
tested program **including the tested program itself** (i.e. argv[0..n]).
It is then up to you to do whatever. In the past others have needed to do
things like remote copy the test executable to the test machine along with
input files and then doing a remote exec capturing the output and
re-echoing the output on the host machine.

You may ask.. That's a lot of work. Why doesn't B2 already do all that for
me? The answer .. It would be a lot of work with lots of fiddly aspects for
all kinds of platforms and situations that a small build system like B2 is
just not the best tool for. :-)
