I'm not convinced these are meant to be the same character. They don't look similar at all except for both being brunette.

Loading screen woman looks like some desert nomad fremen freedom fighter with some sort of massive cloak and a sword. She also has a face tattoo.

Alima is some slave whore who specifically tells you in the game she wants to be owned by a rich merchant and your job is to deliver her to one. She doesn't seem to be a freedom fighter type at all and prefers to be in sex slavery.

I'm guessing loading screen concept art woman is just cut content.
