No, though cows and whales come from a common ancestor being the Pakicetus. Cows are "sisters" to hippos, and both of these species are "cousins" to whales. Cows, like all other ungulates, have their evolution much farther back on the evolutionary tree than whales do. Whales came from mammals that went from being terrestrial to oceanic in a matter of 8 million years. See the related link below for more info.
They evolved from even toed ungulates, or animals with even hoofs like cows and giraffes.
