Just before I moved in to my house 7 years ago a tree in the front garden
was felled and treated to kill it.

I have now dug up the parts of the stump above ground level as it is
starting to rot. The wood was very crumbly, even pulpy in parts, is it safe
to use this wood in my compost heap?

No, very risky. Not worth it for the amount of compost gained.
