That will redirect from "bony fish" to "Osteichthyes", the name of the scientific category that represents bony fish.

And there is a cladogram on that page. And it includes whales, by virtue of including tetrapods (it shows a picture of a salamander).

It also says on that page "Osteichthyes can be compared to Euteleostomi. In paleontology, the terms are synonymous." And "Euteleostomi presents a cladistic view which includes the terrestrial tetrapods that evolved from lobe-finned fish". And yes, as mentioned, whales are tetrapods.

So, while I didn't say "whales are bony fish", I said "whales are members of the bony fish clade", and I'd say wikipedia agrees with that statement. (to be clear, we humans are also members of the bony fish clade) And if you consider bony fish to be a paraphyletic group, well, then it isn't a clade.
