Non HGV usage of Tractor Unit

Hi

I am trying to establish the legality, of driving a tractor unit, without a trailer, with a non HGV licence.

I have been told, that it may be possible, if the 5th wheel is dismantled, therefore no trailer can be attached.

Is this possible, or are there other ways of driving the cab unit legally, without a HGV licence.
