I guess it's only available if you have purchased the laptop in the US or some specific parts of the EU originally, isn't it? At least, I cannot see any way to purchase it or even extend the warranty for my laptop.
I highly doubt such service is provided in Malta or Cyprus, for example, considering Lenovo only has a single authorized service center per each island, IIRC.
I'm living in Cyprus; had a Lenovo technician come here from Nicosia (~150 miles return) to fix my left-side USB ports of my ThinkPad T590 about six weeks ago.
In the past, I've had come Lenovo to remote parts of Switzerland and Germany, as well.
