Yes. Shinohara and Kuroiwa are seasoned Investigators who have seen quite many kinds of freaky shit. They rated Yoshimura's regen as an 8 out of, possibly, 10. So, this means that they've seen ghoul's with higher regeneration ability than Yoshimura. As well as lower. Safe to say, being an 8, Yoshimura can grow reattach his torso.

Ghouls can't regenerate if they are - 1). Damaged beyond their ability. 2). Low on Rc. 3). Traumatised or paralysed with fear by their injuries.

Yoshimura won't be paralysed or traumatised on getting bisected in half. As V's cleaner, he must've been through the murkiest waters, IMO.
