I've purchased a vending machine that companyX produces and has a touch screen.
I've purchased a vending machine companyX produces and that has a touch screen.
Think about the parallelism. You don't need to be thinking of subjects and objects and relative clauses for this question. (And I found all that difficult to follow.)
Neither of the two sentences is parallel. Whatever is after AND must be matched with something parallel before the AND, and neither sentence has that.
We have two pieces of information about the vending machine:
- company X produces the machine
- the machine has a touchscreen
This sentence gives us the two pieces of information in parallel form:
I've purchased a vending machine THAT companyX produces and THAT has a touch screen. Posted from my mobile device
