Sure you can do it that way, but you would need to know range as well, and the farther away your are, the more error you will have.
However, if you can measure the length of the vessel and the height of a known part of the superstructure (such as a mast or funnel), you don't even need the range. That's essentially the method as described in the Angriffsscheibe Handbuch example #5.
You observe a T2 Tanker at long range. Looking through the attack scope, the bow to stern is 7.5 ticks long, and the mast is 3 ticks high, to give an observed Aspect Ratio (AR=length/height) of 2.5 (7.5/3). What is the target’s angle on the bow (AOB)?
This method is less accurate as the AOB approaches zero because the beam (width) of the ship will distort your measurements. If the beam of the ship was zero, then mathematically:
AOB = asin (AR observed / AR reference)
