Most current workers in tyrannosaurid systematics agree that the
"Tarbosaurus" material is not sufficiently different from Tyrannosaurus rex
to be given its own generic name.

See Holtz, 1997 (SVP abstract) for further details.

However, it is important to remember that there are differences of opinion
with regards to low-level taxonomy.  Some people are lumpers, some are
splitters.
