Yes, an Azure Migrate project can migrate to multiple subscriptions (same Azure tenant) in the same destination region. When allowing replication for a machine or a group of machines, you can choose the target subscription. For agentless VMware migrations, the target region is locked after the first replication, and for agent-based and agentless Hyper-V migrations, the target region is locked during the replication appliance and Hyper-V provider installation, respectively.
