According to the information available, discounts from different sources may not be combinable. Typically, when you receive a discount from an event, such as the Microsoft AZ-900 virtual event, it is intended to be used independently. If your organization is offering a separate discount, you would need to check the specific terms and conditions associated with both discounts to determine if they can be combined. It is advisable to contact Microsoft support or the relevant certification authority for clarification on combining these offers.
