Short answer: Yes. ID75 or XD75 pack in a full set of keys in 80% case. Some are pretty ridiculous - BFO-9000 or FU!Keyboard
Long answer: most orthos are designed so that you can hold layer shift keys with your thumbs(RSE, LWR for Raise and Lower) to type other keys(e.g. Lower+J types “-“ and Raise+J types “_”). This way you type the keys of a full layout without moving your hands off home row and with less keys overall.
I don’t know of anything marketed as such, though some ortholinear POS terminals can be easily repurposed into big keyboards. The ortho users tend to be very interested in ergonomics, and one of the guiding principles there is minimizing hand movement (sometimes I personally think this goes a bit far; it seems to me that if it’s good to move the rest of your body from time to time, it’s good to move your arms and hands too). Most of them are quite small. The biggest size I’ve seen regularly is 75 keys in a 15x5 grid. Of course, ortho/ergo is also a very DIY-friendly space, so sometimes you see… outliers. LOL.
Are there full-size ortho keyboards?
