Explicitly promotional push isn't allowed on iPhone to begin with. Only exception is if the user enables it via some setting inside your app, separate from the regular permission dialog, which is really unlikely.
Of course you can just pass off promotional stuff as not promotional, but same on Android, and you have to be sly about it.
