Lenovo really does seem like a fairly rare Chinese technology company with a diverse management team, research teams in various countries outside of China, and a generally "cosmopolitan" attitude. Rather than the blatant and insular nationalism that a lot of Chinese companies seem to ooze these days.
Contrast that with Huawei for example, which literally has direct ties to the Chinese military (PLA) and probably also to various high CCP officials, and is a notorious intellectual property stealer. (For example Cisco fought them for years over appropriation of trade secrets and even after they reached one settlement they later said that Huawei had lied in its presentation of facts of that case)
Whereas I cannot remember a single case of Lenovo engaging in blatant copyright or patent abuse or any other sort of corporate malfeasance other than an occasional sloppiness in some of the software they bundled with their computing products.
When they took over IBM's PC business in 2005 I was very skeptical as I had become very fond of IBM Thinkpads at that point. It didn't take long for that skepticism to fade away. I still prefer Thinkpads and Lenovo is the largest PC maker in the world now.
Yes it's true that Chinese companies theoretically are supposed to help the authorities snoop on people if asked. But Lenovo's field of business would mean that if they ever got caught doing such a thing, it would destroy their reputation and their business. I doubt even the CCP would put the company and their 80,000 employees at risk for that.
