Yes.

Not only can you, you must. You can only make the decision to split when a 10-man squad hits the table for the first time in a game, and you must make the decision at that time.

From Space Marine FaQ, Combat Squad:


You must decide which units are splitting into combat squads,
and which models go into each combat squad, immediately
before deployment. A unit split into combat squads therefore is
now two separate units for all game purposes including
calculating the total number of units in the army, and the
number of units you can place in reserve. Then proceed with
deployment as normal. Note that two combat squads split from
the same unit can embark in the same transport vehicle,
providing its transport capacity allows.

That would incline that you are forced to state how your forces are split before the start of the game, not at the first time they hit to the table.. (Since how they would affect the number of units you can put to reserves if they would arrive at turn 3, and after that affect the limits..)

... why, so it does. That's what I get for remembering the 5th edition answer instead of looking up the answer fresh. Good call.

Yeah, it is back to the way I like to play, with some extra goodies.
