Not if its a true center-tapped winding.  You can still wire a center-tapped
transformer (i.e. this example) from centertap to one of the ends with
120VAC and get 14400VAC output.
However, if you do this (and I don't recommend it), you would have to derate
your transformer's kva rating accordingly.
