It's hard to compare CPUs based on the price of the products they're packaged in. There are obviously a lot of other bits and bobs that go into them. However, it's worth noting that a MacBook Air is $300 cheaper than the list price for the Ideapad 4800U with an equivalent RAM and storage configuration. So by your logic, is it fair to compare the two? Perhaps, a 4700U based laptop would be a fairer comparison?
The gap between the Ideapad 4800U and the base model 14 inch MacBook Pro is a bit wider, but you'll also get a better display panel and LPDDR5-6400[1] memory.
We'll have to see how the lower specced M1 Pros perform, but it's hardly clear cut.
Edit: I just looked up the price of the cheapest MacBook Pro with a M1 Max processor and it's about 70% more expensive than the Ideapad 4800U. However, with double the memory and much better quality memory and a better display and it seems roughly about 70% better multithreaded performance in Geekbench workloads. Furthermore, you may get very similar performance on CPU bound workloads with the 10 core M1 Pro, the cheapest of which is only 52% more expensive than the Ideapad 4800U.
