IQ tests itself are age relative. The tests already take this into account, that's why your IQ is relative to people in the same age bracket. Basically, when you say "my IQ is 100", it's means that you are in the 50th percentile of the peers of the same age. It doesn't have any "absolue" value, and it shifts with the years (100 IQ 50 years ago is not the same as 100 IQ now)

The core problem is if IQ tests are context sensitive. IQ tests are relatively new in human history so we don't know how do they operate (without much changes) in a 400 year timespan.

Yes, though details depend on the exact test and how it's normalised.

Nobody asks you for your age when you are doing IQ test befire giving you your result.

Originally IQ was defined as "mental age" divided by actual age and it was for testing development of children. The actual age was capped at 16. So it was expected for any person 16 and over to have the same result in the test to have the same IQ.
