I think there's too much variance between Lenovo models with the same SKU that it's possible to rule it out for specific models. You might get one without coil noise from a dealer that checks it for you, or maybe you can get a showroom device that doesn't suffer from coil whine. I suspect most users either do not hear it or do not find it that annoying. Maybe there will be more focus on it once fanless (and otherwise totally quiet) laptops and desktops will be more common, so that coil whine turns into an issue that UX designers care about.
