Answer
Breathing through an extra long snorkel while swimming underwater would not be possible because the pressure on the surface is about 1 atm while the diver's lungs are at a high pressure. If a diver breathes with an extra long snorkel at the surface, it would create a pressure difference which would eventually cause the death of a diver.
