yes there is a limit, that limit will vary from one manufacturer to another.

The limits come in 'total length' as well as 'max length and height' or lift of the evaporator section. (or drop of the evaporator as if the condenser is on the roof.)

Under most scenarios total length limits are around 100 ft. or about 30 meters. I've seen some that go up to around 150 feet or about 45 meters. Lift and or drop -- from / to the condensing unit fit within those limits.

If you don't adhere to the limits, compressor failure is the result.

(lack of oil return -- compressor seizes up.)

Let say for example : for some reason, the outdoor compressor need to be place around 80 meters from acsu unit.. is it possible and what need to be done to make it work for that distance.. (please excuse my english as its not my native speak)

No, that's nearly double the distance of the longest lengths I have ever seen. There isn't anything that I am aware of to 'make it work'.

You could do it anyway, but the result would be failed compressors. (lack of oil -- compressor seizes up)

Why: oil is heavy gets trapped in the line set with no way to return to the compressor.
