Can a comma be used before 'and' here?

Is it appropriate to use a comma in these examples?

I know that a comma can only be used before a coordinating conjunction if it connects two independent clauses. But this is not the case here. I thought of this question and wanted to know whether using a comma in these examples is correct.

Please note that example 2 is taken from a novel.
