Laptops are pretty much unavailable with ECC especially with soldered memory becoming common. On the desktop side, there's multiple motherboards that explicitly note that they support ECC memory. AsRock and Asus both include ECC memory on their QVL lists. I'm not sure how many ITX boards support ECC though so getting it on something that's not a tower might be tough.

But it's definitely possible, I have an ECC setup on my desktop and it's caught a memory error or two over the last few years.

Even with the desktop I want to see “ECC guaranteed” on the box, not a pile of parts that “should” work.

		It's hard to get more ECC guaranteed than the mobo manufacturer having ECC ram on their QVL (qualified vendor list) for the motherboard and indicating that ECC is supported in the specs. I suppose you can just get a complete workstation with ECC from HP or DELL and that'll be guaranteed to work but you'll certainly pay a hefty premium for that.
