I don't see a problem with it. Ally is something I've encountered in activist/organizing circles since the mid 90's. Woke is more recent, and I'll be honest, I'm still fuzzy on the meaning.
Example: I have a friend, who is "woke." White dude, heart is in the right place. Moves into a neighborhood (Pilsen, in Chicago) that is undergoing gentrification and displacement of the traditionally Chicano community that has been there since post-WW2. Immediately posts on Facebook about the gentrification problem in the neighborhood, or, calls out an entertainment establishment for their problematic way of dealing with the community and then several days later, I see photos of him trashed at same establishment.
Based on my experience, I'm apprehensive about anyone who uses the phrase "woke." Ally is something that people don't pickup unless they have had some encounter with actual organizing and the academic/professional language surrounding political movements, etc.
