As long as the country you live in does not levy an "exit" tax of some sorts (on the individual, not the company), you should be able to move. Only the individual shareholder is moving, you are not moving the company abroad.

This law does not just apply on the disposition of shares, but on nearly all types of assets, with the exception of property.
