Your question is very meta. The best answer I can give you might be very meta as well.
I have to guess what you mean. If you mean can you have anxiety disorder without having anxiety symptoms like fast heartbeat or other symptoms, then I suppose that is possible.
Anxiety disorder is a large group of disorders that can encompass even obsessive-compulsive disorder, which technically only gets anxious as a result of the OCD.
So yeah, in short, anything is possible. If in doubt, consult a trained psychiatric specialist.
