Here is an LTT video about how many PCI-E extensions one can daisychain without problems.
The limit is around 3 meters.

The RTX 4000 series uses PCIe 5, and the article references PCIe 6.

I was wondering about that. According to Nvidia RTX 4090 product page, it still used PCIe 4.

Yup, it only uses PCI-E5 power connectors. The GPU is gen4.

A meter of extension adds ~10ns of latency (speed of light).
