Of course you can, enterprises are already starting to push "bring your own device". Even if you don't do that, you can still move to the thin client model where hardware failure just means asking the office manager to swap your device with a new one from the cupboard.
BYOD doesn't do away with the problem because the users don't know how to fix them themselves, so they'll still need someone, even if it's a tech at the mall rather than in their office.
