Maybe not. The reach may be very different as well, due to top tube length. And saddle height is going to impact your saddle to handlebar drop...which you may not have stem quill length to compensate for.
I'll also agree with an above reply that at 46cm the geometry may be compromised to fit 700c wheels.
How tall are you?
