A single Acer OEM key should work across multiple devices. No issues expected.
It's unusual. The product key refused to activate after reinstalling Windows via the image from Microsoft. This could be due to various reasons such as corrupted files or licensing issues.
Laptops typically include recovery files for reinstallation. These are obtained from the system recovery partition. If a different installer is used, it must perform an activation step that verifies whether the key is already active through an online check. Perhaps this is the reason.
