I'm assuming you'd want to have playable framerate. Maybe. With a herculean effort, way surpassing tricks and techniques used by x86 PCSX2 and other PS2 emulators. Pure CPU computational performance wise yes. You'd need to have very clever ways to emulate the "Emotion Engine", like VPU0 and VPU1 vector processors. A single RPi4 core would far exceed those, but using it in an emulator might be very hard, because you'll probably need to synchronize execution and to emulate PS2 internal memory model. Emulating PS2 300 MHz MIPS core would be a walk in the park compared with the other issues. But memory bandwidth might be the true showstopper. I think RPi4 has just one 32-bit DDR4 channel at 2400 MHz, which yields just 9.6 GB/s theoretical maximum bandwidth. More than what PS2 got, but the margins for emulation are uncomfortably low. So while it's "possible", I don't think it'll happen at playable framerates. It'd be easier to reverse engineer the rendering engines in popular PS2 games and to simply port them.
