Honest question, as I'm not familiar with swedish law. If a man consents to have sex with a woman that claims to be taking birth control pills and later he finds out she really wasn't, can she be accused of rape?
The issue isn't birth control (alone), but foremost corporeal autonomy (the woman didn't want him to have "naked" sex, while in your example the man wanted to) and to a lesser extent the health risk.
So not taking the pill is not even close to the question of sleeping without a condom.
