No, because a jelly has to be strained of the fruit pulp (it’s why jelly is clear), and the fruit usually has to have a high pectin amount in it.

It would be closer to a jam though. But calling it a pastry would be like declaring your ham is a pastry because you put some apple jelly on it. It takes more than a spread to make it a pastry.

And the pizza dough doesn’t make it a pastry, this is due to how yeast doughs (fermentation, in pizza dough also typically a high wheat protein count) are different from pastry doughs (high fat content, no yeast). To make an example, it would be like declaring a peanut butter and jam sandwich is a pastry. It’s not.
