Hello Chuck,
Hmmm, frozen in the open position presents more problems than if it was in the closed position.
I'd suggest tapping out the trigger pin and remove the trigger and safety catch, remembering there in a small coil spring and plunger under the rear end of the safety which will fly off to never, never land (meaning you will never, never find it.) if your not carefull. You can test some parts to see if they are loose. e.g. If the lever pin and locking screw aren't frozen in place, adjust the locking screw so the lever pin can be pushed or tapped out. Once that is done the lever should be capable of some movement, but it is still attached to the breechblock by a swivel link and screw. Remove the lever spring that is attached to the underside of the barrel, that may well increase some movement. Look at the lefthand side of the breechblock, the link pin should just be visible. If not, then it's another problem to solve, as the breechblock is not fully down so the link screw can be removed. 
With the lever free and removed I would seriously suggest the Ultrasonic Tank cleaning process, this will remove a lot of dirt, rust and corrosion and vibrate it free of the action. 
I trust you have a set of the action stripping instructions?
If not, they can be found in Frank DeHaas's book Single Shot Rifles and Actions, there may be a copy in your local library. There is only one way to take apart and put a Borchardt together, you can't do it by removing all the screws and pins and giving it a good shake. 
Try the above first and get back to me and let me know how you get on.
Finally before you start any dismantling work obtain a plastic box with a sealable lid large enough to keep all the parts in. Keep the lid on at all times, otherwise, sooner or later you, or one of your family will knock it on the floor and you will loose bits and pieces. Don't ask how I know.
