I think Luna's been hiding since Season 1 and that's why Lincoln suggested that they should go with him because Luna will accept the Deliquents who wants to run away from the Grounders but he doesn't know why she's in hiding. (Maybe Luna is known by all Grounders to take in people who wants to hide.)

I think the Polis Ambassador doesnt know that Luna is in The Boat Nation and just like Titus said in 03x09 Lexa gave the order not to hunt her down. Making her safe wherever nation she might hide into and as a nightblood, she can rise as a leader of a nation (who would not want a commander's blood in their ranks just like Queen Nia has one).

For some reason, Lexa doesn't like to talk about Luna in front of Clarke (maybe Luna and Lexa are lovers too) and Luna refused fighting Lexa so she left, branding her a traitor and a coward.

And to think that Luna chose not to fight means she would be against "Jus drein Jus daun" something that Lexa enforced so strictly before and a good reason for Clarke to pursue her to become the new commander.
