Can I change a UoM key to business user requirements w/o changing the technical UoM key (and dimension assignment)?

Yes.
In general, this is possible. A UoM is defined with a technical key and a commercial key. The commercial key (as the technical key) has to be unique but can differ from the technical key.

Example:

Business users require UoM LTA (Long ton, in air) and TOA (ton, in air) to be displayed as LNT and MT.

Go to UoM customizing transaction CUNI and select the appropriate dimension ID (Here: WGHTA, weight NSW):

Change the commercial keys as required:

The new keys are displayed in the calculations:
