Old Core i5-520m: TDP 25w or 35w?

I have an old Arrandale Core i5-520M from 2010.

When I look it up in Intel's ARK it lists a 35w max TDP but when I run CPU-Z it gives the max TDP as 25w. Maybe I missed something but I thought, outside of more recent chips, the TDP is the TDP, no wiggle room to play with.

Can OEMs configure these older chips for a different TDP? I'd really appreciate if someone has a link to a technical document somewhere talking about this. The laptop is a HP EliteBook 8440p if it matters. Thanks!
