I doubt it.
Your swift strikes ward off enemies attacking nearby allies.
Prerequisite: Combat Reflexes.
Benefit: When an adjacent ally is attacked, you may use an attack of opportunity to attempt the aid another action to improve your ally's AC. You may not use the aid another action to improve your ally's attack roll with this attack.
Normal: Aid another is a standard action.
Bodyguard doesn't mention aiding anything other than AC.Further, "when an adjacent ally is attacked" is clearly intended to mean "when an adjacent ally's AC is targeted by an attack".
I realize this sort of diminishes the usefulness Aid Allies to certain types of allies (such as someone with Snake Style), but Aid Allies is merely reiterating the standard Aid Another options, making it clear that it applies to all types of uses. Bodyguard is simply 1 type that has a specific limitation on how it modifies Aid Another.
