There are 21 different trees. I was just messing with the Cave of Dragonflies generator and was just wondering if any two trainer IDs and Secret IDs produce the same 4 Munchlax as another.

Yes. You can prove this trivially by recognising that the number of combinations of Munchlax trees (21 choose 4 = 5,985) is less than the number of unique TID/SID pairs (above four million).
Furthermore: Munchlax trees are selected using division and the modulo operation (more info; also explained byTCoD itself), and of course different numbers can have the same quotient or remainder. This is another way to convince yourself there will be clashes between distinct TID/SID pairs.
