Yes, but this is not recommended. It’s best to have one pending petition at the time. For example for the O-1 with premium processing and one approved and if there is enough evidence, submit the EB-1A. If there is a situation where the I-140 of the EB-1A has been approved and we are in the process of I-485 and still waiting for the EAD, we can file for the O-1 so that the applicant can start working asap.
