TXV compressor with orifice tube/piston coil
It will work but you need to know what the old condenser was or at the very least what size piston is in the evaporator right now.
You will not know anything about system charge until it's hooked up and opened. Whomever very well may have pumped down the refrigerant into the compressor of this Lennox you now have. You can VERY SLIGHTLY unseat one of the service valves to see if anything comes out but very quickly close it off.
That's about as far as you can go until it's opened up into the lines. Copper refrigerant lines can easily be extended to reach wherever they have to, just braze some length onto what's there. You'll need to remove the shraeder valves before brazing condenser in to avoid melting the seals. Re-install the valve cores after a few minutes, once the metal has cooled off a bit, pull a vacuum down to 500 microns AFTER nitrogen pressure testing and cleaning and finally let any possible remaining refrigerant into the lines. Your gauges will let you know how much you have.
