It's not the weight that's a problem, so much as the non-static nature - you're going to be constantly hanging, removing and jostling the bike/rack and each of these micro-aggravations are going to dig the anchors further in to what is essentially a paper-lined sedimentary substance. It'll be fine for a year and it might be fine for three years, but there's not much of an excuse for not doing it right when all it takes is a plywood board, some screws and a drill (and maybe a paint roller if you're concerned about the appearance).
