Is the Endurance implant "free?"

By this, I mean, the Endurance implant gives you +1 Endurance. The number of implants you can buy is limited by your Endurance score. Does the +1 you get from this implant allow you to get an extra implant?

Solution 1:

Turns out the answer is, "no." Adding an Endurance implant will take up one of your original Endurance slots. However, it does confer the hit point bonus.

Also, in case anyone asks, adding an Intelligence implant does grant more skill points at level-up.

Solution 2:

No, but the Intense Training Perk - when applied to Endurance - does allow you to get another implant. This allows you to pick up 2 SPECIAL points for the price of a single perk.
