When a virtual hard disk is first created, while not technically an empty container, it is essentially an empty container meaning that it neither partitioned, formatted or flagged as bootable and at that moment not capable of being booted. It remains in that state until it is either manually partitioned, formatted and flagged as bootable or done so automatically while an OS is being installed.
So it depends on what you consider as bootable however considering the actual state of a virtual hard disk at the time of its initial creation the answer is no. Meaning as an example if you use vmware-vdiak manager and create a virtual hard disk with it then the object created is not bootable and cannot be made bootable during it initial creation as it is not partitioned, formatted or flagged as bootable at that moment. It requires additional steps beyond the mechanism that creates the actual virtual hard disk files.
Now if one then partitions, formats and flags as bootable the once empty .vmdk file then one might now consider it bootable however one might also not consider it bootable until and OS is installed.
IMO the virtual hard disk is not bootable when first created however becomes bootable once its partitioned, formatted and flagged as bootable which requires steps beyond the actual creation of the virtual hard disk however once done the virtual hard disk while at that point technically is bootable nonetheless it will not boot as no OS has been installed.
