Yes, but you'll probably need a shitload of lemons and a shitload (each) of zinc and copper elecrodes. Each lemon one would serve as one battery cell capable of providing about 1 milliamp of current; you'd want to wire your lemons in parallel so as to provide a large current. Don't know how many amps is required to light off steel wool, but probably not much.
