Massively simplified, your vasculature is part smooth muscle. Tone is the amount of constriction held by these muscles.

The word "tone" is used in a few places in medicine usually holding the same meaning.

One way to look at it is tone is a way of saying how tight or loose something is. More tone being tighter.

Increased sympathetic tone for example, the sympathetic nervous system is stronger vs decreased tone making it weaker.
