If the 6.8L Triton® V10 can safely be rated to pull 26,000 for coach; why is it restricted to 23,000 for 27B / 29M with same engine? Don't try to tell me that those little push / tow tractors - tugs at the airports are limited in pull if they have same engine with only factor being the size of the tug.

Because it's not just about the engine and not just about pulling. You have to engineer the transmission, rear end, suspension and frame. That's why there are F53 chassis with different GVWR as well, 16K through 26K and maybe higher.
