Alan, Yes. Part 97 Rules require that the Control Operator be able to shut down a repeater in the event of a malfunction, and this can be done over a radio or wireline link. A link that is used solely to exercise control need not be a full-duplex link, and it can even be one-way, so long as it works. For example, you could have a 440 MHz receiver that would pass only a carrier with a specific PL or DPL code, followed by a simple DTMF decoder. You could key up your control radio and send a brief string of DTMF digits to knock down the repeater or bring it up. You could also use DTMF to change power levels, switch antennas, or unlock the door.
I strongly suggest that you enable your repeater's timeout timer and set it for no more than three minutes, in accordance with Part 97.213(b). This will ensure that the repeater will shut itself off, even if the controller or control link fails. The most recent edition of Part 97 is dated October 1, 2003.
