To avoid under-25 charges, can I say I'm travelling on business when renting a car?

I need to rent a car for personal travelling(SUV), but I'm only 23, and they will only provide me a fee waiver for being under 25 if I'm on business, under my company's contract, can I just say that I'm on business?(or are there legal ramifications?)

I'm pretty sure if i ask my company's travel agents they will say that i can't, since that's the safer bet for them, but was just thinking of people actually do this... and if there is a way for them to find out if i'm actually on business or not?
