You can grow a Bottle Palm in a container. This Palm is quite slow growing and does not have a large root ball.
For this reason I do not see any need to plant the Bottle Palm in the manner you describe.
This type of planting is done for invasive root systems that the Bottle Palm does not have.
Here is a link with more information.
