If the wire is already in a conduit, you'll have to move the outlet along with it, which means you'll need to disassemble part of the conduit, find the connections somewhere, and check the insulation condition. It's not exactly impossible, but if you don't know exactly where the cable runs and how it's secured in there, you can easily damage it. Then you're looking at a non-working outlet, risk of a short circuit, and potentially danger for everyone in the house.
The easiest thing is just to grab a long grounded extension cord and run it carefully along the baseboard or behind furniture. When you're picking an extension cord, make sure it has decent, thick insulation and not too many adapters on one outlet - they overheat. Secure the cord so you won't trip over it and nothing presses down on it.
We lived at our dacha for a long time with one outlet in an awkward spot, so I know how inconvenient that is. But you should only move it if you're confident in your abilities or can call someone who's done this before. Otherwise, saving money on an electrician will end up costing you more.
