I have straightened a wall, and this resulted in the wall becoming thicker than what the recess for the round window allows.
The plan was to have OSB + 13 mm plasterboard, but now only one layer fits.
The wall is straightened with 34x45 on cc400.
Will this be sturdy enough to tile on?

Are we talking kitchen or bathroom? In bathrooms, very high demands are placed on rigidity so regular gypsum is not suitable, and most waterproofing materials do not allow regular gypsum behind them.
In kitchens, 13 mm gypsum might work. But there are wet room boards that are much stiffer than regular gypsum, such as Hydropanel or Fermacell (available at K-rauta).

Well, according to the latest rules, plaster is once again allowed in bathrooms, but not in or near the shower/bathtub. Check the regulations at bkr.se for details.
As for stiffness, I believe single-layer plasterboard should be mounted with studs at 30 cm centers to be OK. There are variations from plasterboard manufacturers. For example, Gyproc has a wet room board intended to be used in the shower zone. In its standard version, it follows the same rules as regular plasterboard concerning stud spacing. But there is a thicker variant, I think 15mm, that is OK for single-layer plasterboard on 60 cm centers.
Just read the post a bit more carefully. These "studs" that are 34x45 used for leveling, how are they attached to the wall? 34 mm offers no stiffness at all, but if they are securely fastened between attachment points to a wall behind, it might be sufficient.

The room is a future laundry room, so it will not become a wet area in its true sense.
The studs are mounted with approximately 400mm centers using shims.
Even though there is thicker gypsum, we won't be able to use it as every millimeter counts. I will rout a small rabbet on the back edge of the round casing to insert the tile a bit. However, since the tile is 10mm thick, I am considering switching to thinner tile closest to the window, like mosaic which tends to be thinner.
