Essentially, center-cut bacon is just regular bacon with the fatty ends cut off. Honestly--you're often paying the same price for less bacon. Regular bacon is longer with the fat still on the ends. Center-cut bacon comes from the same section of the pig; it's just a shorter cut.  You can, obviously, sub in regular bacon. Feel free to snip off that little extra bit of fat, although, when cooked and drained, you'll lose quite a bit of that fat anyway.
