No, it should be separated, because there are pathogenic bacteria, parasites, in the toilet drainage, which will swim upstream and enter the kitchen.
There will usually be a reserved sewer drain that can be used as a washbasin drain if there is no other purpose. If you want to make other reserved drains, you need to reconsider a tee, keep this mouth and turn the elbow into a tee pipe, you can find a suitable place to place the washbasin (wash basin) at will.
What kind of material is the pipe, if the pipe is aging, replace it.
For the riser of the kitchen and bathroom, it is best not to use the wooden keel that is easy to deform and not fireproof as the riser skeleton, but to choose a high-quality light steel keel.
