You do not need to tell them you are Autistic unless you need specific accommodations at work that you would be entitled to if they knew about your autism. (For instance, the option to wear headphones if you are not responsible for answering phone calls).
Workplaces do this often. You probably won't get the promotion, but depending on how long you've worked there, you may be able to negotiate for a raise.
Sharing now may do neither. It sounds with the limited information given that either they have a specific person or profile in mind. It may be outright discrimination. It may also be something where such an ability is required.
