No. Unlike fish, whales and dolphins move their fins up and down when swimming.
Think of the fin's motion as being related to the spine's motion. A fish's tail fin moves from side to side because it moves its entire spine from side to side when swimming. A whale's tail fin moves up and down because the animal's spine is moving up and down.
Whales and dolphins (called Cetaceans in scientific jargon) evolved from land-dwelling mammals. When a mammal walks and especially when it runs, one can see its back moving up and down. The Cetaceans retained this up-and-down spinal movement when they moved from running back to swimming.

Whales, because their legs become vestigial for modern day whales. Their legs start to shrink slowly on the ancestors of fossils related to the whales, which slowly evolve to fins.
