I doubt it. It's listening for the 9 tone on the other end and I think it can distinguish between the two.
This reminds me of a hack we did in my freshman dorm though... we cut the wire from a card reader to a washing machine and recorded the signal the reader sent. Then reconnected the card reader to the washer in parallel with an 1/8inch audio jack. The folks who were in the know would plug their iPod into the audio jack on the back of the washer, play the "free laundry" mp3, and get a free load of laundry.
