No it cannot. But I drain my water heater tank by opening the low point drain and opening the pressure relief valve on the hot water tank. All 6 gallons will drain from the low point drain. I'm not sure if there is supposed to be a check valve on the water tank inlet that prevents this from being able to happen, but is always how I drain my hot water tank and useful info if I ever found myself in a jam and needed access to that water.
