After spending hours looking for an answer on this, I come to you with this question.
What editions of Office will run on Windows LTSC?
I have resellers who want to purchase Windows Enterprise LTSC and run Office on it. For example some want to run Office 2019 Home & Business. There is no document I can find against this. Why/how is it a customer cannot run Office ProPlus on LTSC but can run any other edition.
Microsoft contradicts itself in multiple places.
Of course, Microsoft states
"The Long Term Servicing Channel, which is designed to be used only for specialized devices (which typically don't run Office) such as those that control medical equipment or ATM machines, receives new feature releases every two to three years."

This plus the above article stating that Office ProPlus is not supported on LTSC
"Effective January 14, 2020, ProPlus will no longer be supported on the following versions of Windows. This will ensure that both Office and Windows receive regular, coordinated updates to provide the most secure environment with the latest capabilities.
- Any Windows 10 LTSC release
