No. Well, if you meant could TC act as a crappy LSD that acts nothing like a real LSD? Then, maybe.

Traction loss. ABS knows. Locks the spinning wheel.
So, open diff, spins the other wheel instead. LSD. Many gradations of ABS before lock.
TC and LSD are two different solutions to similar but different problems. ABS does not "lock" the spinning wheel - ABS can only apply the brakes and at the limit of brake lockup, the ABS intervenes. Now you've gone from a wheel that was loosing traction and spinning to a wheel that is nearly skidding while under maximum braking. At the wheel/tire, this isn't the same effect as an LSD which is based on sensing the torque difference between the two rear wheels, not the difference in wheel speed.

I suppose TC/ABS could be considered an approximation of an LSD but its not a very good approximation.
