No, there is no support for reducing the size of a VMware VMFS volume. An alternative solution would be to migrate all virtual machines to a different VMFS volume, and remove the original LUN. This will free up space for creating a new, smaller VMFS Volume.
For detailed information on migrating all virtual machines to a different VMFS volume and removing the original LUN, refer to VMware Knowledge Base Article# 2004605 - Unmounting a LUN or Detaching a Datastore/Storage Device from multiple ESXi 5.x hosts.
