Why not?
As a GM? I personally am quite liberal about any weapon mod that makes sense.
But the key phrase there is "makes sense". Collapsible swords or blades that can be broken down into small pieces don't make sense. Memory alloy ones do, so I actually house rule those in as a mod option, but not the others. It's not about "game balance" - goodness knows that in 4E, melee characters need all the help they can get. It's about my ability to suspend my disbelief, and my desire to maintain a semblance of near-reality (because magic) through abstraction.

No, i believe the Spur does not grant the +1 reach and can not be dropped/thrown right?
I want, basically, on the back or in the leg where you would usually carry a gun, just something i can store my sword in.
And if it is in a metal leg or torso anyway, good luck finding it in there. The Cyber-Holster grants a +2 concealment bonus, something like that for a sword.
I was joking, but then again I had also thought that
you were.
Simple point I'd like to make about a cyber-scabbard: even putting aside the physical difficulties of fitting such a large space into a cyberlimb, note that anything large enough to hold and conceal a sword is necessarily going to be large enough to hold and conceal most Longarms.
Cyberholsters are
small. They and their cousins, Large Smuggling Compartments, can't hold anything bigger than a pistol. And if they or any other cyberimplants
could, we'd have sammies running around with undetectable assault rifles stashed in their limbs (...somehow).
Now, if we're talking a memory alloy blade? One of those "scabbards" could easily be accomodated, because the blade becomes "foldable" and you can coil it up in a small space or snake it around inside a cyberlimb as necessary. But if you're trying to conceal a long, rigid blade of metal inside your body, the only real option is to impale yourself, and even then it probably won't all fit.
Anyway, if all you want is a blade weapon that can be concealed in a cyberlimb, as well as detached and thrown, then get a Projectile Spur from Augmentation. They even come with a bonus superhuman "Throwing" strength of 14. You won't get the Reach, but oh well. (If it was large enough of a weapon to deserve reach, it wouldn't fit inside your forearm, now would it?)
