No, it cannot. Currently a freighter can only move prefabricated Planetary Defence Centres, which are built disassembled for exactly this purpose. An orbital habitat sits in orbit like a giant space station. It cannot be built in sections and must be built as one from the industry screen.
The only way to move a habitat is to build it at your industrial center, then move it into position using on-board engines or tug boats (tractor ships).
