No, HOWEVER, you can "pass" a variable from an Order Guide to a triggered Catalog Item.
Say you have "Rotisserie Chicken" yes/no variable on Order Guide and you want to invoke a UI Policy on a Catalog Item called Stock Refrigerator.

You simply add the same variable on the Stock Refrigerator Catalog Item and then use what's called an Item Variable Assignment.  As you can see by this form, you can link an Item Variable to an Order Guide Variable assuming they're the same data types.
