No, they could not interbreed.

Explanation:

When a group of squirrels separate from each other and develop its unique characteristics, this is known as speciation. One type of speciation is allopatic speciation in which one squirrel's species separate into two separate groups and isolated from each other because of the physical barrier. This physical barrier can be a mountain range or waterway and makes it impossible to breed with one another. Each squirrels species develop unique genetic characteristics due to change in habitat and genetic variations are transferred to their offspring.
