No you cannot.
that key is only used to unlock the door or trunk from the outside, or lock the glove box.
On the C280, the trunk is electro-mechanical. It should open either with the key fob, or with the "valet" key that slides out of the fob. The C-Class Mercedes' still have the traditional exterior keyhole. Also, on the C-Class, there is a switch on the center console between the seats that opens the trunk.

After running my regular key through the wash, I have been using the "valet" key. Other than the fact that I must manually unlock the doors, it seems to work well. I drive an ML320. Besides, the valet key fits better on my key ring.
Do you have the "valet key" (black FOB key with the auto-lock & 'panic' buttons are)? We had this problem with our '98 E320 and it turned out the battery in the valet key needed replacing.
You can't. The valet key doesn't have the capacity to do more than it does and you can't add capacity to it unless you have the standard key and even then it would take skills beyond most people's ability.
Take the spare/valet key out of it's holder on the fob. In the slot, under where the head of the valet key is stored, is a grey slide lock. Using the valet key or a similar tool, slide the gray lock under the body of the rest of the fob. This will unlock and push up the top of the fob. Pull out the internals and replace the battery. Two CR2025, in my key.
Push the button. Use the electronic /remote door/lock opener. Use the key. Or use the toggle on the counsel inside.
The 1999 Mercedes C280 came equipped with a 2.8L V6. Symptoms of a bad or failing fuel pump include abnormal priming noise when the key is placed in the ON position, humming noise, sputtering, and ultimate failure to start the car. The OER Cambiare fuel pump is #VE523075.
Its a valet key because it does not allow access to the trunk and glove box.
To replace a Mercedes outside door handle, first the door grommets from the inside of the door panel must be removed. Then, inserting and turning the key allows the handle assembly to be pulled out and replaced.
