Easy to tell, with horizontal the wheel skewer will be positioned below the chain stay rather than directly behind it.

Doesn't stop you using it as SS. Google 'single speed with vertical drop outs ' there's a few options.

'Scuse my ignorance, but why can'f a SS have vertical dropouts?

i think you can, but a chain tensioned is needed…

This is what I'm trying to figure. I put some monster forces through my rear cassette and it doesn't budge, so if I just take the derailleur off and shorten the chain, what's changed? This is obviously hypothetical, because there isn't a cat in hell's chance I would do this!

Car boot trawling is great fun , i have been quite lucky but often go months at a time with no finds then 2 or 3 in one go so just got to stick at it

If your rear dropouts are vertical, with a SS you've got no means of keeping the chain at exactly the right length / tension, so it will be bouncing around as likely slightly too long to be able to join a full link. Chain tensioner easily sorts this.
The whole point of singlespeed is to simplify the transmission. If you still need a pulley tensioner, why not stick with a rear derailleur.
There are some chainring and sprocket combos which, with the right chainstay length, provide sufficient chain tension with non adjustable dropouts. Horizontal dropouts or rear facing track-ends allow you to select the gear you like and can account for chain wear.
