I'd think that gluing the wood trim to the exposed particle board edge would hold well; probably better than gluing it to a laminate edge, depending on the type of glue you use. Common wood glue, i.e., Titebond, should bond the wood trim to the particle board OK.
Do you have a source for the edge trim stock? If not, you'd need to buy the proper wood somewhere & mill it to the size & profile that you want. Either way, I would expect that aligning the edge pieces to the tops might be difficult, especially if they're sort of long. If you glue on the edge piece, and parts of it extend slightly above the laminate surface, it would be hard to trim or sand the wood down without damaging the laminate surface. Not impossible, but not something I'd enjoy having to do. And if the wood is lower, then you have the laminate edge exposed; not much you could do about that.
If I were doing it, I'd route a slot in the edge of the top, and a matching slot in the trim piece, and use a spline to ensure alignment. And use a LOT of clamps.
If you can post a picture of what you're working with, others here may have some better advice.
