Or the old trick of using a smaller pipe inside the cut off old one of
course.

I am having the outside of my house rendered so everything has to be
removed from the outside walls. This has all gone smoothly except for one
solvent weld pipe (40mm), it has a right angle into the drain but its
connected inside the wall which means the pipe work is too close to the
wall to get the render behind. Is there any way to connect to the corner
without digging out the wall or damaging the kitchen to bring it out
20mm.
Thanks

They don't easily disconnect unless they have been badly made joints to
start with. Easiest would be to cut the pipe inside well away from the
wall, or disconnect if there is a compression fitting to the waste.
Pull out the pipe through the wall from the outside and after the
rendering is done replace the outside pipe and the one through the wall.
At some point an extra joint may be needed if all the outside pipe is
solvent weld, and it may be possible to put a coupler somewhere
inconspicuous. it will be necessary to open up the hole in the new
render and make good round the new outside elbow. With mortar or
acrylic caulk for outside use.
