In general, yes, but there are some nuances.:
1. If the company is registered in Frison, the owner can apply for a work visa without any nuances.
2. If the company is registered in Mainland, then in order to apply for a work visa for any employee (including if the owner wants to apply for a work visa), the company must already have an Emirates ID from one of the owners or the director.
That is, if, for example, a company has 2 owners, then first the first owner issues himself an Emirates ID as the owner of the company, and only after that he "hires" the second owner to work for the company and issues him a work visa.
Or, if there is 1 owner in the company, then he must first make himself an Emirates ID as the owner of the company, and only after that he can "hire" himself to work for his own company and apply for a work visa.
