Probably not. I assume that Freeza's enhancements aided him in his 100% stamina drain, as he wouldn't be so confident if he was going to fight someone aware of his greatest weakness. SSJ, whilst not having as big of a stamina drain as 100% Freeza, still depletes Ki pretty fast, so I doubt that having only just attained it, Goku would be able to fight in this form for a long period of time. Freeza's Nova Strike also has a greater amp than the Kamehameha, so the only skills that Goku could possibly trump Freeza with are the Taiyoken and Kienzan (assuming he knew the latter at this point).
Though Goku still has some chance of winning with his greater fighting talent, I'd still give it to Freeza about 6 or 7/10.
