Yes. Family terms are the same as L-1A — L-2 spouses are employment-authorized incident to status, children may study but not work — but the five-year ceiling changes the household's planning horizon.
Same rules, shorter runway
Because the dependants' position is identical between the two sub-categories, a household comparing them should not weigh spousal work at all. The question that does matter is what happens at the end of five years, and it should be asked before the move rather than during the fourth year. Map the children's ages and school stages against the ceiling and see where the family would be when it arrives.
Then ask what the realistic options are at that point: a different classification available on facts that will exist by then, a return, or something else. Building the evidence for an alternative route takes time, so identifying it early keeps the choice open. Families that leave the question until the ceiling is close usually find that most of the alternatives required preparation they did not do.
