Flying with no transponder...?

My friend and I are doing some work (avionic upgrades) on a 1978 Cessna 152. The aircraft is parked on a private field and we need to move it to his own private strip to do the work on it. We purchased it at its current location but the panel had been cannibalized and it has not been flown for some time. A mechanic has deemed it safe to fly on its reposition flight and my friend and I have done extensive run ups with the engine. The aircraft has no transponder. We need to fly in 7 miles to the destination. Can we legally do this without notifying the FAA?
