Engines shed a lot of metallic particles, rag lint, and sealant squeeze out during the bedding in process. Lycoming recommends an oil change after the first 10-hours now days. This is a change over from earlier years where the oil was changed every 25-hours when only a filter screen is used. They have all pretty much gone to 50-hours now as long as they have a spin on filter which most now have.

I'd change it. As was mentioned already, oil is cheap compared to the cost of repairs and overhauls. If it has detergent oil in it, warm it up good before you change it. Detergent oils hold the crud in suspension and you want all that crud to go out the drain plug.
