my gut says yes because they tend to use plurals in the transport rules but maybe I'm jaded by other editions so now I'm not sure.
is there anything that says yes or no explicitly one way or the other?

There is no restriction on how many units can embark. The rules are based on models embarking.

The only restriction i see is how many models a transport vehicle can carry.

Bear in mind this restriction:

* Every Dedicated Transport unit from your army must start the battle with at least one unit embarked within it, or it cannot be deployed for that battle and will instead count as having been destroyed during the first battle round.

from the Select Units stage of Muster Your Army (page 56 of the core rules)

So the implication is definitely that a transport can have more than one unit in it, and dedicated transports must start with at least one unit embarked.

I can second every answer I have seen to this post.

A transport can carry any number of units, as long as all the models can fit into the transport at once.
A dedicated transport has to have its own unit in it at setup.
It doesn't have to be the only unit in it at setup.

F.X. a space marine rhino can have 12 infantry models in it. The rhino can only be taken as a dedicated transport. You buy the rhino for a 5 man tactical squad. This squad HAS to start in the rhino. Their buddies, the next 5 man squad, can ride along with them, as can two characters, for a total of 12 models.

1. You don't buy dedicated transports for units. You just buy the dedicated transport and have to have something in it.
2. No such thing as a 5-man Tactical Squad anymore. Tacs, stupidly, have to be 10-men strong and that's it. It's one of the reasons the Razorback has become almost unusable in 10th.
