Can you? Yes. Is it likely to work? Depends on how with it they are and if they will allow you to do it. As long as you are able to get a good seal then yes you can do it in a chair but will run into the same issues as above.Can you use a bvm on a conscious patient? How about conscious patient sitting up on a chair?

I still remember call I did early on in my career:
Respond for the 80yo with SOB. She's tripodding in the kitchen, 1-word answers, but hey, she doesn't look like she's in thaaaaaaat much distress... We throw a NRB on her and carry her out to the truck. By the time we put her in the back, she has completely stopped breathing. Oopsie daisy!
In retrospect, she probably didn't look dramatically sick because she was so far down the decompensated side of the curve, and was running out of energy to keep up with her breathing. We took her out of the tripod position and put her on a stretcher in Fowler's position, and it was just too much.
She was mostly conscious and alert, just not breathing! Pulled out a BVM, got behind her and started bagging. Sats came up, CO2 went down, imagine that! That was the only time I've used a BVM on a conscious patient sitting up in a chair, but it seemed like it worked well enough. It's tough to do while the ambulance is moving though - you're semi-squatting behind the head of the stretcher, bouncing around, trying to keep a seal...
If only BVMs came with straps like Anesthesia masks. BVM +PEEP @ 15 lpm works great, if you can maintain a seal, on conscious patients in severe distress as you are setting up your NPPV or preparing for RSI. Or if you NPPV masks are non-vented you can just use that.
The service I work for uses the Flow-Safe CPAP. Those masks connect to a BVM without an adapter, and I've had pretty good success with it. The Flow-safe masks + some PEEP and high flow O2 can also make a poor-man's BiPAP if you can get the bag squeezing timing down.I remember stealing a connector piece from the ED at some point to be able to hook up our BVM to whatever brand of CPAP we used. Don't think I ever actually used it though.
