Cufflinks are not meant only for the exec level but anyone can use it.It's an accesory for a shirt.
But in working environment try to not offend or dress anything ahead of your seniors just for your own "safety".

Try imagine your boss drive a wira to work and you driving a beemer to work, 10am you park your car at the parking lot and walk down from the car just to see that your boss just park his wira beside you, though it's ok for you to drive a beemer but he might feel you are more over than him which might offend him .

Back to topic, if you wearing a shirt which need cufflink then use it. No problem at all.(Still the same thing, try not to offend you senior or make them feel you are trying to climb over their head, unless you really meant to do that)
