No. Trisodium phosphate is Na3PO4, but tripotassium phosphate is K3PO4. Potassium (K+) is not the same thing as sodium (Na+), even though both are attached to a phosphate (PO43-) in this example.
Basically another name for diammonium hydrogen phosphate is just diammonium phosphate. So by mixing these two similar chemicals together, there would be definitely no chemical reactions.
