Probably not, because the evidence itself is not created in a vacuum. There is no objective way to measure IQ "stuff", so depending on the methods picked you get wildly different results
So first off, no shit the college board things the SAT measures good stuff, it's their test.
Second nobody said the SATs don't measure something, but that something is ability to take an SAT test which is highly predictive of how well you can take other tests. Which as our society puts lots of stock into tests isn't nothing but it's not measuring anything inate.
