Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Unfortunately, once a Microsoft 365 Business Premium benefit from Microsoft Startups has been redeemed, it cannot be reversed, transferred, or re‑activated on another tenant. The redemption permanently associates the benefit with the tenant where it was initially claimed. This means Microsoft cannot “un‑redeem” or move the benefit to a different account or directory.
Since you have mentioned that the subscription is unused, you can try to open a support ticket directly to Microsoft support via Microsoft Admin Center by following this article: Get support - Microsoft 365 admin | Microsoft Learn. In case the benefit cannot be moved, you will need to continue using it in the tenant where it was redeemed.
