On the other hand, Torque (Newton*metres) when multiplied by
Radians (metre/metre) does give Energy (N*m*m/m - N*m), but only
after reduction. And for sure, Torque (N*m) is not the same as
Energy (N*m).

Torque is the same as work. Work is energy conversion.

So sometimes it is appropriate to say the reduced results are the
same and some times it is not. Is there a way to know when it is
legal?

Yes. Sorta like knowing when it's legal to carry the one. ;-)

What rules have you used to conclude that reducing V/m/A/m to V/A
is appropriate?

Meters cancel meters.

I recently saw somewhere on the web where a given light intensity was
converted to the equivalent free space voltage and current. I think it
was a response to Dr. Slicks inquiry over on sci.physics.electromag.

.....yes, here it is.
