No, since who holds what coin is defined by consensus, which has to stretch out of the mining pool. If they arbitrarily gave themselves coin, for example, then no other client would accept that they hold that.
See smtddr's reply for details of what they can and cannot do.

- VMG 13y agoyes, ever other Bitcoin client would refuse the blocks because they don't follow the transaction spec The purpose of Bitcoin mining is to establish an ordered sequence of transactions
- guard-of-terra 13y agoThis will cause block chain to split into two (we've already observed that a year ago due to sqlite glitch between versions) and the offender (ghash, 51%) will get exactly 0% in the block chain that every other client will be using.
