Probably not, what with it being an airborne radar system measuring relative altitude. But if you know the actual altitude of the airborne platform and the local pressure conditions based on recorded met data it doesn't take a genius to do some sums. Either way its fairly irrelevant as the 737s CVR will have recorded its altitude which was obviously the same as the Legacys.
