That technically isn't Leto
I wouldn't be surprised if they did cut it, though more because how Phoenix's Joker has completely eclipsed Leto's Joker so they don't even want any direct nods to Leto or his imagery especially because
Birds of Prey is coming out in the peak of awards season where Phoenix is a frontrunner (also note how in the main trailer Harley's illustration of Joker which she uses as a bullseye looks nothing like Leto's version).
Also, at this point WB seems to be done with Leto, especially after his behaviour towards Phoenix's Joker film.
