This template returns the list of lookup names with items on the book that have notes. If none do, return the empty string. If you want to use it, make it a stored template and call it in the icon template.

I don't know if the performance will be acceptable, especially if lots of items in lots of columns have notes.

python:
def evaluate(book, context):
	db = context.db.new_api
	notes_on_book = db.items_with_notes_in_book(book.id)
	return '' if not notes_on_book else ', '.join(notes_on_book.keys())
