Yes, you can use seduce this way. Of course you can!
If the object of your desire is even a little bit interested in you, or curious about you - and you're a hot badass of Apocalypse World, who wouldn't be? - then you can use sex as leverage. And if other circumstances - responsibilities, commitments, shyness, duty, prejudice, fear, expectations, barriers of inconvenience - would normally stop the object of your desire from approaching you, then you can use that leverage to get him or her to ignore them.
My opinion is that the world is made up almost entirely of people who are a little bit interested in each other, but normal, reasonable, appropriate barriers (and some unreasonable, inappropriate ones) keep them from approaching each other. When you seduce someone, you offer them what they want - sex with you - and they have to decide whether to cross those barriers to get it. That's exactly the way the move works.
If you don't have to make the move to get somebody to have sex with you, that just means that those barriers don't exist. You're both single, into each other, from the same side of the tracks, and the lights are low...
