He can but he will not. We think that the early mined coins of Satoshi are created as a prize competition (Re: Maybe Satoshi created the greatest prize competition https://bitcointalk.org/index.php?topic=5150688.0) and that Satoshi is waiting this coins to be moved. We also think that he will not respond when somebody moves the first coins but it will be a message to the Bitcoin community that the private keys are somehow on the blockchain. Satoshi could move the coins (2009/2010) to P2PKH addresses but did not.
