"Can't hurt" and "no problem" are not related phrases. "Can't hurt" means "will not do any damage" or "will not cause harm". "No problem" means "there is not a problem". Ex: Although I'm on a diet, eating one bite of cake can't hurt. Ex: This costs more than my budget allows, but I'll buy it anyway. Spending a little more money can't hurt.
