Problem description:
How do I make it so a user randomly spawns in one of the four corners of the map? (my map is 40x40)

If it's 40x40x1:
mob/proc/SpawnAtCorner()
    x = pick(1, world.maxx)
    y = pick(1, world.maxy)

Thanks.

Another question: What's the code for spawning at a random turf?

You can use lists containing each turf.
var/list/turfs=list()
//...
//add turfs to the list
//...
if(turfs.len) //if any turfs were added
   var/turf/T=pick(turfs) //pick a turf from the list
   loc=T

Or you know..

loc = locate(rand(1,40),rand(1,40),1)

Basically the same thing Pop said, except including everything in between..

I'd prefer to make invisible turfs of X type that are always spawn points. They can be placed anywhere.

var/spawn_count = 0

SpawnPoint
    parent_type = /turf
    var/number = 0

    New()
        spawn_count ++
        src.number = spawn_count
        tag = "spawnpoint_[src.number]"
        ..()

mob/proc/spawn()
    var/turf/T
    while(!T) 
        T = locate("spawnpoint_[rand(1, spawn_count)]")
        if(!T.Move(src)) T = null

What about random spawning only at non dense turfs?

I actually forgot about the block() procedure, and I used it in a project just yesterday :P

block() returns a list of turfs in a 3D "block" of space on the map.

So, using the way I said earlier...
var/list/turfs=block(locate(1,1,1),locate(40,40,1)) //All turfs within the block

//Below is the code to remove any dense turfs within the block.
for(var/turf/t in turfs) //for all the turfs in the list
   if(t.density)//if the turf is dense,
      turfs-=t  //remove it from the list.
//---

var/turf/t=pick(turfs)
loc=t

Or if you want to check if there are any dense objects in the turf...
//The allclear() proc. Checks if a turf is undense and anything in it is undense.
turf/proc/allclear()
   for(var/atom/t in range(0,t))if(t.density)return 0
   return 1
//Just replace if(t.density) to if(!t.allclear()) in the example above.
