There may be hope for it. Brake fluid is an effective paint stripper, and much milder on plastics than a proper fit-for-purpose paint stripper gel. The keyboard would need to be disassembled and the logo covered up first of course, but it would be worth a try.
Hell, depending on how the price looks nearer the end, I may throw in a bid on it. I don't know how much success can be had in cleaning it up, but I'd at least be safe in knowing that I couldn't make it look any worse.
