Well, there is a potential option but I don't like to suggest it because it very quickly gets used for shady purposes.
Build your video, definitely remove the audio and upload it Private first. If it is going to be matched by ContentID, you will know right away. In that instance, you can elect to delete it.
Copyright strikes (ie long term punishments) are a manual process and thus require someone to pick your video out for removal. So, you will be able to take the video down quickly enough that no strike is reasonably going to happen.
Honestly, game companies are unlikely to strike for a trailer. In fact, I've yet to hear an example of that occurring. They will however strike for early content, so if you happen to get Arkham Knight early, be very very careful and wait until the release date before upload.
As long as you are being genuine in your fair use application, you could well be fine. It's just the ContentID side that is frustrating to deal with, but even if it is registered with ContentID, that's still not an overt punishment. Just means they're not letting you get ad revenue for it.
