No.
529 distributions (withdrawals) are governed by federal law. Any distribution consists of both basis (contributions) and earnings. You are not allowed to withdraw just contributions.
For example; if you have $10,000 in your account consisting of $6000 contributions and $4000 earnings, any distribution will be 40% earnings. So, if you take a $1000 distribution, $400 of it will be earrings. If the $1000 was not used for education, the $400 will be taxable income ($600 will be tax free). The $400 will also be subject to the 10% penalty (but not the $600).
