Smaller razors and hollow ground razors, it would be very difficult.
Firstly, you'd lose enough carbon in the edge part to make it unusable.
Now, suppose you'd protect the blade with a thin clay coating or heat treating paint or something else, the quench is still very likely to turn your blade into something that vaguely resembles a ribbed potato chip. or a banana.
Your blade is in the middle. It looks like it is half hollow so it could go either way. It looks a bit thin around the edge but with protection it might just work. Or not. :)
That said, it would be interesting to try. After all, the razor is ruined already, and it looks like it has some material to it. If you'd care to give it a try, un-pin the razor and mail it to me and I'll do it for free, just for curiosity's sake.
