Yes, that would work. We could borrow text from here:
Marshall Undead (Su): Once a day, a bone tyrant master can call undead to gather towards it. This is resolved like a use of the tyrant's Subjugate Undead ability (see below). Marshal Undead can affect any undead within 20 miles of the master, except for other bone tyrants, and does not require line of effect or line of sight. The marshaled undead count towards the Hit Dice limit of the bone tyrant's Subjugate Undead ability.
Affected undead start walking towards the bone tyrant master, taking the most direct route available. A marshaled undead will try to move around or break through obstacles, and will attack creatures that threaten or obstruct them. If the Subjugate Undead check had a "rebuke" result, the undead will walk towards the master for 1 hour and then revert to normal behavior; undead marshaled by a "command" result will keep walking until they are destroyed or the bone tyrant master instructs them to stop (either in person or via a bone tyrant minion).
