Hi, Anna.

You can also say that Iā€™ll finish it at lunch time, canā€™t you?
ā€œfinishā€ in this case is transitive verb, so you need object(work or it).
But if you use ā€œfinishedā€, you donā€™t need object as it is an adjective.

These useges are different, yes I know but
I just donā€™t see any differences in their meanings.
