Is there any way that I differentiate between them at this stage

Why do you need to differentiate them?

Just plant each tray/pot load in a separate row.

As they grow, the onions will develop tubular hollow leafs whilst the
leeks will develop flat leaves.

Leeks aren't to be planted until they are about the diameter of a No.2
school pencil,

Why is that? What would be the problem if they were planted when they
had a much smaller diameter, say, like a cocktail stick?

Don't think it's a diameter problem really, except diameter has a
relationship with length. (Usually the greater the diameter of the leek,
the greater it's length. This is the way I've seen it presented in
books. Basing it on length would avoid the confusion that we are
discussing now.) You want 5 - 6 inches of the plant in the ground to
produce the blanched (white) base of the leek.

Thank you for a very clear answer. I will in future base my decisions
on the leeks having about 6 inches of growth before transplanting out.
