If it's the quicksave and you haven't saved over it multiple times since then, yes. Otherwise, might I suggest storing a copy of your Oblivion saves folder somewhere else on your computer, once in a while. That's what I do when I get bored of one character and want to play a different one, every now and then. Then I can go back to the first character when I'm bored of the second one, etc. That also helps to ensure I can rely on another backup in case I make the same mistake you describe in the OP.
Edit: unless you save your game through console command every time, I don't think there is any other way to recover the save, unless it was the quicksave.
