Microsoft officially supports Windows 10 22H2 on every CPU supported by previous versions of Windows 10; Windows "Supported Processor" lists are for OEMs building new PCs, not end users updating existing systems.
According to the current supported processor list, the oldest Intel CPU supported by Windows 7 was introduced about 5 years after Windows 7 itself [1].
