I would think not. Not only does it have the wrong valve on it (gasses uses different valve, so they don't get mixed up..) but the tank is probably not rated for "cryo" - which is what you need for when you store gasses as liquids.
CO2 is stored as a liquid at room temperature - due to the pressures involved. Helium can't be liquefied due to conventional pressures, and you have to chill it to about 470 below zero Fahrenheit to liquiefy it due to temperatures.
While the tank can probably handle the pressure used (~800 psi, as I recall,) it would probably fail due to temperature.
However, this would still be worth checking out - take it to a carbonics place and ask them, since they deal with compressed gasses all the time.
