Could I upgrade my laptop processor from Intel i3-4030U to Intel i7-4510U?

Could I do that? Also, is any CPU with the same socket compatible?

No, laptop processors aren't upgradeable, even if the sockets are compatible. That's because the laptop processors' sockets are soldered on, you can't remove it without destroying it, or using special equipment.
