No, it is not admitted to do so. Art. 27 CopA applies only if the work of art is accessible to the public because of the will of the author. In this case the sculpture is on public ground temporarily because it is transported from a place to another, and not because of the will of the author. If the same sculpture was exposed on a public square in Lugano, visible to everybody, in accordance with the author, then the exception of art. 27 CopA would apply.
