Not particularly relevant. The only TPM that counts is TPM2, which was 2014 for the specification. Not even all “TPM 2.0” implementations are considered sufficient. Plenty of devices even in 2019 were being built without a TPM2 that would qualify for Windows 11, in part because the industry didn’t know that it was about to be required, in part among those that tried not knowing their chosen implementation would still not qualify.

No, since I mainly use Windows and replace my laptop at least once every 10 years.
TPM has existed in laptops since 2006
