No.

NO.

NO NO NO NO NO NO NO NO.

Umm, no.

It is a coelurosaur.

It was included in Coelurosauria back in the 1920s, than was called a
"carnosaur" in the 1930s until the 1980s (because, like Allosaurus, it was
big), but various researchers demonstrated in the late 1980s and 1990s that
tyrannosaurids are just gigantic coelurosaurs.

Carnosaurs, and coelurosaurs, are both parts of Avetheropoda, which is part
of Tetanurae.
