If there is a possibility this is CCA treated wood, it is not a good idea. This is the "green wood" treated lumber common for the past 40 years of so. It was used for exterior wood to resist rot and insects. CCA stands for Chrome-Copper-Arsenic- the 3 metals used to treat the wood. Smoke from this wood is extremely unhealthy. I would not use it.

"Treated wood can be soft or hard." But, generally what is bought from a lumberyard is soft.
Pressure treated wood can last up to 20 years or more and most pressured treated wood sold in stores such as Home Depot offer a limited lifetime warranty.
Dry wood is usually easier, but wood will dry much faster when split. If you have the time to let large sections dry first, it will be easier to split, but it may take a year to dry. Wood that is split and stacked to allow air to circulate will be dry and ready to burn in about 5 months.
Preservatively-treated (pressure-treated) wood does not meet the standard, unless the wood was heat-treated and stamped HT prior to preservative treatment.
