I can think of a number of big differences. Hibernation is a total body function that involves many organs including the brain, heart, kidneys, etc. But a coma is a brain problem. Hibernation is a desirable natural adaptation to deal with the natural environment. Coma is a pathology, a sickness, something undesirable. And unlike a coma, hibernation is self-induced.
