You might, but expect about 500k-720k of errors, or more. You don't know what's under there, first of all, and you don't know how the drive will act when it finds no track there. Will it slip to a different track, and only format 720k, while telling you it did 1.44? Also, the whole may be for MAC single sided drives, so you can use both sides of the disk. I think some places still make disks that way.
