Greetings Jeff,
No, it is not too late to transplant this white spruce. One can typically transplant deciduous and conifer trees from the point of leaf senescence (dormancy) up to the point when the ground freezes.
Personally, I am an advocate of late winter/early spring transplanting because I feel that fall transplants sustain a higher incidence of winter injury and dessication compared to trees transplanted in late February, March, or early April. The "literature" is mixed on this view; however, I still feel that late winter/early spring transplants fair much better than fall transplants.
Best of luck!
