不可以.
句意：他上大学的梦想是否会实现还是未知数.
因为 句子后面是 uncertain 即不确定,可能梦想成真,也可能梦想幻灭.
如果是肯定的回答或者否定的回答则可以换成that.
具体的用法可以参考doubt.
一、doubt用作动词
doubt+宾语从句
（1）在否定句和疑问句中,doubt后面接that引导的宾语从句.例如：
I don”t doubt that he can finishthe task on time. 我相信他能按时完成任务.
Do you doubt that she willsucceed? 你怀疑她会成功吗?
（2）在肯定句中,doubt后面一般接whether或if引导的宾语从句.例如：
I doubt whether they can swimacross the river. 我怀疑他们能否游过河去.
He doubts if she will keep herword. 他不敢肯定她是否会遵守诺言.
注意：在肯定句中,doubt后面也可以接that引导的宾语从句,但表示疑虑较大或“不相信”.例如
We doubt that they can completethe work ahead of time. 我们不相信他们能提前完成这项工.
I doubt that he will come.我看他未必会来.
不能!
