Of course it's possible if you buy from a reputable breeder that shows their dogs in conformation and knows their lines. The problem with most "pet quality" breeders is that they are breeding dogs with less than perfect coats so the puppies will of course not have a proper coat either. Also, I didn't think yorkies were supposed to have "cobby" bodies
Cobby makes me think of my persian cats - big boned, broad shoulders, compact bodies. When I look at most show yorkies, they seem to have a good amount of length to their legs.

Purchasing from backyard breeders, pet shops, and puppymills perpetuates the suffering of other dogs.
Educate yourself and buy from reputable breeders or rescue.
