No, there is not an equivalent word since split compound words is the norm in English.
The compound-word-splitting is a hassle in Swedish because all nouns are either one word (rektor - principal), a hyphenated compound word (e-post - e-mail) or a compounded word (sjuksköterska - nurse).
The last example is a Swedish compound of sjuk (sick) and sköterska (carer). As one word it means nurse (a carer of the sick) but if you split it into two it means a sick carer.
In Swedish you can create new word by compounding them to change their meanings. However, splitting compounded words into smaller pieces can change their meaning or, in most cases, make them loose their meaning completely.
E.g. a lorry truck driver would just be written as one compounded word in Swedish: lastbilsförare. Splitting last, bil(s) and förare into three pieces would not make any sense; they still have their separate meanings but it would be like listing words without any connection between them. It’s like someone would write “I’m a lorry, truck, driver” – you would probably get what they mean but it would be annoying reading texts like that. Or, like in the example above; is the person in question a carer of the sick (nurse) or a sick carer? Either that person stated their profession or their health status and profession, however, you can't always be sure if it's as the text says or a spelling mistake with some compounded words when they are split up.
Btw, the s in parentheses is put between some sounds in Swedish to make the compounded words flow better.
