You can't tell, that is why it's best to not play around if you're on BES. They can track everything, BlackBerry Messenger, SMS, e-mails, etc. My BES guy saves information for two years on the BES servers...
There is no way from the phone to tell if you're being tracked. But just because the ability is there if you're on a BES, doesn't mean it's being done. If you're on a BES and you're friendly with your IT department, ask them.
If work gave it to you, assume you are being tracked and behave accordingly. I drive OTR and like many companies, have a Qualcomm terminal in the truck. Not only my employer, but also the shipper and the customer, can see my exact location at any point.
If the capability is there, expect it's being used whether it's acknowledged or denied.

make friends with the SysAdmin running your BES server. Even if they're not a wealth of info they're great at making things work. If you feel your being tracked and that paraniod, turn off the GPS features and buy a Garmin / TomTom for your car. It's also nice to have the Sysadmin on your side to tweak Security Policies that otherwise might restrict some of the cool things you can do on your BlackBerry.
