Yes, But you don't have to change the firmware. All you have to do is
clone in a trunking codeplug using Lab and it will work. If you clone in a
trunking codeplug and then do the Service-Command Board replacement
procedure it should work fine. Before you do the replacement procedure, be
sure and write down or print out all the alignment values (called Alignment
Summary on the print menu). Using the command board replacement procedure
reinitializes the processor.

If you want to go one step better, you should actually change the model
number in the MLM and Command Board to one for a trunking model. (see
Batlabs on how to do this).

Can I change the firmware in a 128 conv spectra to a trunking type?
