Can I start with GK2?
Yes, based on the current public record.The official pages do not require a completed GK1 save. The demo is the safest way to judge the new controls and loop before buying.

What is actually different in Graveyard Keeper 2, and whether you need to finish the original first.
Quick answer
No official prerequisite is stated. GK2 puts you in the role of the Grand Inquisitor, moves to a fixed-camera 3D world, expands zombie automation and adds Town restoration and undead-army combat. Playing GK1 still gives useful story and systems context.

The differences come from official listings and developer diaries. The recommendation to play GK1 first remains personal, and the linked Steam discussion shows that players disagree.
