Took a while to find it in the
DE codex, but it's on page 91, in the description of Dedicated transports.
In other words, Dark Eldar units are indeed restricted by only being allowed to opt for a dedicated transport if the squad could fit into it.
As for deploying the two separately... I can't find any rules that force you to embark the squad in the vehicle during deployment... so I suppose it's feasible.
