Can we include code from free Unity published samples in assets ?

I would like to include some of the code from Procedural examples, to showcase particle emission from procedural meshes in Particle Dynamic Magic v1.2

Is it possible ?

Here is the asset

Just the Perlin noise and the releavant script, maybe the procedural texture script too

I will change them to C# code of course and name them differenty so they do not conflict if someone already has them in the project

Would also probably inlude the lightning script too
