有关that作连词的问题
Realizing that I wasn't going to get much chance for promotion,I soon became bored with
my work.和 Please note that I will be away from Boston next week,in case you want to call me and discuss things.中的that是不是引导同位语从句且可否省略.

两个都是引导宾语从句.第一句that I wasn't going to get much chance for promotion是realizing的宾语,第二句that I will be away from Boston next week是note的宾语.那为什么说I wasn't going to get much chance for promotion是主句Realizing是伴随状语其主语要和主句一致整个Realizing that I wasn't going to get much chance for promotion都是伴随状语,是以realizing为中心的现在分词短语, that I wasn't going to get much chance for promotion是realizing所带的宾语从句。
