Yes, it depends on what you mean by "version"...presumably (hopefully) security patches are being done.
Whether that matters depends on the system design. In a typical embedded system, most vectors for malware don’t exist. The network connection can be directly to a master controller; there can be no USB ports or accessible removable media storage devices; and so on.
Of course, if somebody designs the system on the assumption it will be on a completely private network and then just puts it on the Internet, all bets are off.
I bet you 50 bucks there is a usb port on our payment terminals, that is no more inaccessible than an easily picked lock away.
