Well yes and no. Some things you absolutely can do that with. But not a lot of people realize just how common it is for industrial devices and applications to still use older chipsets. 486s and pentiums still in use today. Simply because by modern standards they are relatively low power tried and tested basic designs. And when you need a discreet portable device. Virtualization often isn't really useful. One could argue why don't they make a wireless dumb terminal of some sort tie back to a central system with a bear minimal system on it just for displaying information. But in noisy industrial environments that really isn't an option. I do see some vendors Etc starting to use Android based devices. But it's a slow change over. And only just starting.
