Is it possible for my tomato plants to get a disease from an partially over-hanging oak tree? The oak tree has reddish spots on its leaves just like the spots on the tomato leaves.

It's technically possible for disease pathogens to travel from one plant to another in the garden, especially if the plants are touching or water is splashed from leaves onto another plant. Some fungal and bacterial diseases have a wide array of hosts, rather than being limited to just one kind of plant. Healthy plants are less susceptible to disease pathogens. You might want to reevaluate the site where your tomatoes are growing. They thrive in full sunshine, where there's ample air circulation. If your plants are stressed from lack of water (trees have thirsty roots and will rob the soil of moisture and nutrients), or they don't get enough sunshine, they may be ripe for infection.
