No. There would be technological fossils, but they would not be interpreted as such, or they would be assumed to be much younger than their actual age and created by their ancestors at a remove of historical not geological time.
I am, of course, assuming that scientific geology arrives at the same point in technological development as here in the real world. The point at which technological fossils here would have been found, scrutinized, and identified as evidence of a civilisation tens of millions of yours ago, corresponds to the early Victorian era. (Post industrial revolution, steam engines widely used, research into electromagnetism under way but not yet applied to technology).
You might be able to hand-wave a different order for scientific advancement which brought scientific geology forwards into the medieval era. Unlike many other sciences, geology needs only simple tools and the scientific method. Here, geologists had worked out that the Earth must be at least a billion years old, while physicists insisted that the sun could not have been "burning" for more than fifty million years. Unusually, the physicists were wrong! Both, of course, were bitterly opposed by biblical literalists in the churches (who in earlier times, would probably have burned the "heretic" geologists at the stake).
Technological fossils would mostly be either ceramic artifacts (artificial metamorphic rocks), or metal artifacts that created voids in rock when they dissolved, later filled with some sort of mineralization by groundwater. Eventually they might even find a piece of once lost gold jewellery (gold alone of the metals, would not dissolve away, and diamonds really are pretty much forever).
