Highly doubtful, since it's more than a month after the purchase now. You could go in and talk to a manager who might let you, but I wouldn't count on it.
PS, since I know someone is going to bring this up; technically the machine and the iPod have to be on the same receipt for the receipt to be eligible for the rebate. The manager can print a new receipt with the machine's model number, change the price to $0, and sell the iPod concurrently.
