Merge One to One Relationship Into Single Entity

I have two entities, Highlight and Location, that have a one-to-one relationship with each other. Location has just 2 properties, start and end. There is no longer any reason for Highlight and Location to be separate and I would like to just merge it all onto Highlight.

Is this possible to do a migration (e.g., mapping model)?
