不可以啊
That he finished writing the copsition in such a short time suprised us all.
That he finished writing the copsition in such a short time 必须that在句首,引导主语从句的,这句才能做主语
suprised 谓语
us 宾语
或者可以这样说
It suprised us all that he finished writing the copsition in such a short time.
It 做 形式主语,真正主语还是 that he finished writing the copsition in such a short time

你给出的句子是定语从句，that指的是前边的整个句子（he finished writing the composition in such a short time），他在很短的时间内完成了作曲，这件事让我们很吃惊！
that引导的定语从句在后边的句子中作主语。。。
你说的意思我不太明白。。
希望我的解释能够帮到您。。。
若有不明白的地方欢迎继续提问...

如果放在句中的话是such...that的句型，但that后面要加一个主语才行，也就是说：
He finished writing the compo...

he finished writing the composition in such a short time 作为使我们惊讶的事物，是动词surprise的主语。主语从句，he 前用that。而surprise 还应有时态变化。

变成这样？That he finished writing the composition in such a short time surprised us all.
可以这样啊，That he finished writing the composition in such a short time变成一个主语从句，从句中的主干成分是完整的，但还是必须要一个引导词，这是主语从句的特征，that不能省略。
