Can i install a virtual copy of OSX 10.14 on a mac running 10.13 using Virtual Box?

Ive got some mission critial legacy software which will only run on OSX 10.13.

I have some other software which will only run on OSX 10.14.

To get around this issue i want to install OSX 10.14 on my laptop using Virtual Box. But i cant see from the compatibility specs if i can install a virtual version of 10.14 using Virtual Box.

Dose anyone know if this is possible ?
