It may be that at the time you would need to raise a support request depending on the scenario.

If both organisations are merging into a single tenant, then if the tenant already has 'with Teams' licenses regardless of Business or Enterprise, then they should be able to buy new subscriptions/licenses with Teams.

Where a completely new tenant is being created and you are licensing it from nothing, then that's a different challenge. This is likely where you would need a support request, with evidence of the merger, the fact they already have with Teams licenses etc. And you are of course dependent on the current whim of Microsoft support.
