can one screw into a tree without doing harm?

Zero.

Wrap the tree with whatever that stuff is at the garden shop; looks like
cardboard, and use spring-loaded clamps to hold up the lamp.

But don't penetrate the tree - it's like ringing the dinner bell for
diseases and parasites.

Good Luck!

Hey, you better call every one who has ever cabled a tree and let them
know. They must not have been aware of that.
