Yes, but is it worth spending the required resources? If the answer is yes, than anyway the 4 digit pin isn't more secure (you can watch people type them and find out the code).
You can change your code. The fingerprint is a bit more difficult. That's my main issue with biometric security, revocation of compromised credentials (e.g. fingerprints) is difficult or impossible.

Not only that. With fingerprints, you are essentially using the same password everywhere. You just need to lose it once and all your accounts would be compromised.

Whyever not? They might have a copy of it lying around. http://www.theguardian.com/technology/2015/sep/23/us-governm...

When it becomes easy - and it will become easy, there's nothing basically hard about printing out some ridged plastic - it will become commonplace. And unlike stolen passwords, an attacker can be fairly sure that you haven't changed your fingers.
I think this misses the point. Accessing a device using a "cloned finger" (not tremendously difficult) can be done without the target ever knowing it has happened.
The wrench technique, less so.
